Not happening, Nobody takes this down track til I get some hard runs in it, Will chop up chassis and sale parts off before put someone else in seat.

Damn sure not putting anyone in a car I built that is having a handling issue, Besides dad gets mad everytime I put him in questionable situation, Happened time or two,LOL

Not like car has never gone straight or always had issue. it has made few lom 5.teens which is .2 to .3 where should be with small motor in it. New one is 60ci and 3:1 more compression should go little quicker.But got to get it back to where was before get more out of it or drop[ in bigger engine. well and new rods too.

Hell lil brother just wrecked his VW at Farmington month or so ago on 155 mph pass. Was becuase of chute picking ass end up when deployed.

Please explain how can not be alignment? I mean if tire is out to right it can not make car pull that way until steering input and then back after removed? Heck guess no reason to set alignment or question if tire not going to effect direction during run. Explain

Two reasons. 1. Because you said you have 1/16 toe in and it is easy to measure on a dragster and hard to screw it up. Actually between Zero and 1/4" will work as long as it is not toed out. 1/16" is good.
2. Because when the car is toed out it does not pull to one side, it will go one direction then go other way always looking for a guardrail. Same with slop in the steering. But it does not pull just to one direction.

You said problem was pulling to the right. I said that is chassis flex, (or bent), Rear steer or rear out of line. Or one rear tire larger diameter than other. Period. That is what causes it. Unless you have a four link then it could be adjustment.

Now if your steering is not correcting it that is another issue as myself and Dave have said there is not enough weight on front end.

I never said it was not responding to sterring input,I have stated it goes to center with steering but once go back to neutral it goes back right.Yes checked steering which is how found slop even thow barely feel at wheel.

I also did not say not possible need wioeght. I said I was over the weight I was told I needed in front by a fairly FED knowledgeable guy. By good amount too. According to video it is not pulling front end any on leave which would not expect as soft as tune was.

I think right now the little slop in shaft joint which can see at steering wheel but barley and is 3/8" free movement in front wheel out side measuredment is issue.

I suspected rearend or tire first thing, Only reason I measured rearend again and again, zfrom every diriction or combination of directions one can imagine. If 1/16 difference I can niot find it. Tires unless changing during run are about as even as one can get rollout wise.

Plan is to make next run with steering joint welded or splined shaft in place of cross bolt.Hard to believe a hole with bolt passing thru 3 pieces of tubing can have any movement,but it can, No holes are not sloppy. Will deal with if need to get cross bar out later. Stenght steering biox mount since does flex some under load. Weight crazed guy used little less material than should have when fabricating mount, Yea same guy buying almuinum lug nuts,rep-lacing all non stress but with aluminum(hey at $2 not lot more cost than heavey steel) making aluminum intake bolts with aluminum nuts.
If car does not go straight, Swap tires side to side. If goes left bang have problem. If goes right now something else. Then throw weights in front, 2 ways to do so, More fuel tank has another 2 gallon capacity. Also also 5 5lb bars drilled rerady to mount Behind battery since it is at fron as far as noxe will allow even built new nose piece to allow max movement.

Again I never dismissed ideas unless have checked them already. Spent friday night checking stuff till 3 AM after getting home from track at 11:00. So most of 4 hours with tape measure and seamstress tape. Hell even bolted laser to rear axles to check rear alignment with front of car. Did find 1/8 to 1/4 there over 20' and that depended in whre in chassis and how held tape. So feel very confident in alignment and center of rearend.

Since all thing rearend center issue. if have idea how to check other than following let me know and will check asap.
Motor plate to rear side to side.
Diaganol measured same
Pinion to frame
rotors to frame
Motor plate to wheel studs
Laser on axles to front end. laser to frame behind wheels and to spindles

Rollout only way I know is same pressure and tape around center of tire same as have doen thousand times. It is every round with A/Fuel and top/fuel.

AT least it is republicn car going right and not libertard going to left. Again a upside in everything.

Concerning the bolt in the steering shaft.
I assume this is a RED where a 2 piece shaft is used to facilitate easy removal when the use of a anti blowback stop is in play.

How to fix and/or improve the bolt slop.
1: Slide another piece of tubing over the hole section> weld.
Drill and ream for a just fits.

2: The bolt must not be something from the hope box. You do not want threads contacting the tubing, ever.
Either hunt down an appropriate NAS bolt
OR take a longer bolt and cut it so only the shank touches the tubing.

This is gospel for every bolted connection on any race car. NAS bolts are your friend.

Only part different than Daves post, it is fed, It is in **** pir, I have bolted in cross memebr steering mounted, Allow to remove transmission from top, exactly same as every funny car ever had. I have main shaft with inner sleeve welded to one side other slides over it and then have sleeve ths slides over main shaft, one hole drilled thru all, I did cut a bolt to fit so no threads touching shaft and have a washer I have to use because shoulder comes thru outter sleeve. There are 4 u joints in shaft but not cheapys All connections at u joint are weleded except one,

Oh and as to easy to measure, Well would be if tank not in way of rear measurement but tanks is as far forward as could get without rack and pinion being in tank. Have to pull tankl to check.

I also checked king pins/spindles for any camber or caster differences, ,3* off on one or others.

Wow, that's a lot of joints. Not that there is anything wrong with that.

My 200" altered/funster has 1 between the steering box arm and the king pin steering arm. It's a male/female fork affair as it only needs to move in one direction.

Steering shaft in middle of coarse. Have to angle down and out then back along chassis to about 2/3s up then angl;e to center and then back to rack and pinion. Not much way around it
When had SPE box or funny car style with drag link ended up abpout ssamer amount of connects except all push pull not roatation motion. Hell used sas, preces in rack and pinion with some modification,

Just put ⅛" to it and send it .
It will not hunt .

As stated above but a lot of post, Plan is try just that first, then swap tires if not issue,Than bolt on weight. If find is weight i will be looking for what to move forward so can remove it.Maybe add fire system with bottle left front.

Torn between doing all in ine shot and doing one at time. If all then remove one at time until right turn clyde. If do one at time then diffently know which was issue.

Will be stiffeniong steering box mount and tightening shaft and hopefullyu get zero slop. All or none could be part of issue.Actually think only one could be contributing to it and in monor roll if any. All needed regardless if issue or not.

Would it do any good to find out how this trailer tracks so well...when it wants to?

https://www.facebook.com/reel/1534054744860166

So are you saying a single wheel on front is answer?

I had something else to post but did not want tio keep throwing post up.

Dave thanks for NAS comment. I did nit thank about it being lot tighter fit. I eneded up replacing quite afew bolts. Down side was first site I found with NAS bolts also had lots of ti Bolts. While I know I am not allowed to worry about weight on bracket car and god help doing so before correcting this. It did cost me little extra to replace certains one with NAS ti bolts,Actually not lot more.

Yea not fixing right turn clyde crap but did tighten steering shaft connection.Pretty sure 3/8" measured front edge of wheel movement with zero sterring wheel movement reomved not going to do anything but help.

NAS bolts.
Why do I make a big deal about this? Wideopen sees the difference now.

How many have growled about their 4 link not responding to changes? Could it be?
How many struts are held on by hardware store bolts?
Motor plates, brake calipers, heim joints, and on and on.

It was the early 70s.
I became a convert about this with my first FED jr fuel car (nitro). I was next up behind a friend of mine in his FED. I could see and hear the car accelerate and then blip, blip, blip, silence.

Then more bad metallic sounds as the car more or less rolled erratically down the track.
From my vantage point the tires looked weird and moving in ways they should not.
There was a trail Of oil behind the car for a couple of hundred feet.

Seeing that something was terribly wrong the track crew reached him just as the car finally stopped.

I saw the guys run up to the car and lean in. They then backed away and one lost his lunch. I'm watching this play out and getting a really bad feeling. He was dead.

Later, I was allowed to take a look at the car.
The bolts that hold the rear end solid to the frame had sheared. There was also only one bolt above and below the rear end. 2 above and below was the norm.

One of the sheared bolts was still handy. Grade 8 full thread. As I recall they were only 3/8".
1/2" should have the minimum.

The rear end had rotated several times while he was strapped in. Look down at your crotch and picture that.

My Friend was well to do for a young 20 something and could have the best of everything. This really made me mad at him at that moment

After the police and EMTs did their work I went to the tower and looked down track. That streak of oil I mentioned...it wasn't oil.
It was blood.

It had been a nice day but clouds rolled in just then and a rain squall happened.
I watched it clean the track of the blood.
Then the Sun came out.
At that point I sat down and bawled like a baby.

This is the first and last time I have told this story.
Do you feel lucky?

Now thats how you make your point on what wrong bolt can get you.

Have heard same or siumilar accounts of others in fed. If ever owned FED you know the number one question. How you sit there with your junk over rearend. I am married my standard answer.

I do have NAS bolts for places like rearend for more sheer resistance along with anti rotation device. Did not think of making other things better fit.If shoulder fits then threads leave room in hole. I did step up from #10 to 1/4" only way to tighten w/o replacing.

I was helping a semi-clueless fellow with his wiring and he brought up that question.
He had a low rider top sportsman car where the seat really isn't that far off of the pavement and a tall aluminum driveshaft tunnel.

I looked at him, looked inside the car, looked back and said to him..
"You do realize that the driveshaft yoke is darn near in line with your hip and nuts?"

I swear the dude went ghost white. He did add a second DS loop before going out.

While I am on a roll, another driveshaft story.
Best friend had a Fiat altered with a sprung rear end. One day the driveshaft parted company.
They spent the rest of the day looking for it to no avail. Very twilight zone weird. It was only about about 18" long.
Fast forward a week and he walks in with the driveshaft in hand.
"Where was it?"
"In the car."
"Say what?"
"It bounced off the track and straight up into and through the aluminum floor panel behind the seat and stuck"
"That was lucky."
"More than you can imagine. It stopped about an inch from my spine."

Not paranpid about driveshaft but do go little more than required. I have to of the clamps for fronmt and red collars, Rules capp for .060 aluminum minimum cover, I have a almost 1/8 thick 2 mpiece tube. The shaft takes knowledge to get out as it is in the trans output collar and against pinion nut with about 1/2 play locked down to 3/16.
If failure in front would have to bend driveshaft to get out. If rear itr would have to beat way out of cover and then out of front to cause real damage,gthat being beating on Chris.

Rearend is 3/16 moly somewaht square build with 8 7/16 bolts 4 per side and two at bottom anti rotation.

Not scared just not stupid regardless what some here think.

Funny story on first question. I won 25 buck bet on how many out of first ten would be that one question. 7 out lof 10
