Pull to right on accel

[blkblk63ss]

Drove car yesterday and it reminded me that it is still pulling to right when i accelerate. It has all new suspension front and rear and i double checked ball joint's lower with load off and upper's came with new tubular arm's i put on.I checked the rear and all is tight with all new bushing's. i have raised rear with the air lift bag's in spring's . My pinion angle on differential look's normal. slightly tipped down. MHRP had a post that his was pulling left after replaced suspension. My suspension is all stock in rear except track bar and it did this from day one driving. When my frame was blasted and painted the guy noticed the frame was torn where the upper control arm attached and he welded it back in and look's like it should. It only pull's when harder acceleration ,drive's straight otherwise with no pull. All help appreciated!!!!

What are your alignment settings?

This might sound stupid on my part,but I can't tell you what caster is for sure. I did alignment's for 35 year's and since I retired I set it up myself at home.(don't trust the so called align shop's). I set camber straight up and played with caster till it drove straight It pulled to left when I first started setting alignment.. I set toe 1/8 in. I used straight edge on each tire measuring with two tapes front and rear of tire. I centered the gear box and lined to that with toe. I have the upper tubular arm's with extra built in positive caster. Like I said it drive's straight ,no pull until harder acceleration.In all my year's aligning I have encounter pull's left and right which never caused a pull on accelerate . Usually braking would make pull more pronounced.

Torque steer is what I am getting for a rear wheel drive car. You would swear there was something loose the way it act's. I have a single spinner differential..........

This is mostly normal on hard acceleration Don.I can't remember when I didn't have to put left input to the steering wheel when leaving the line on a street /strip car.Even my fwd Cavalier would do it.

I have to saw the wheel too under hard acceleration but thats cuz mine is striping the asphalt

Shouldn't you check the ball joints with the front end loader?

Well maybe I am over expressing acceleration ,on a medium acceration it does it .I don't remember any of car's I have owned did this . I had a new 63 and 64 back in the day and they never did that.

yes I understand that kind of acceleration where you have to fight the wheel.......

I put the jack under control arm next to tire ,and I have checked by jacking under center of frame . Either way I have no looseness, everything is new.

Don, when you say track bar, are you referring to the Panhard bar?Is it adjustable, or fixed in one position?

Pan Hard bar, that is adjustable . It did it from first time i drove it with all original component's. PS. I mean original front rebuilt a arm's and rear rebuilt pan hard bar.I have replaced those .Every thing is new in suspension ,sorry if I did not explain that right.

Sounds like torque steer from the rear end. Single upper arm will cause this with enough horsepower, or possibly rear control arm bolt holes are worn oblong from years of use & holeshots.

 

[skipxt4]

Don, make sure the panhard bar is adjusted correctly, or your car will dog track. I had a similar thing happen to my 64 one day, when the nut, holding the bar, to the left side of the frame, loosened up. I turned the corner, on my street and then nailed it, and the car was all over the road.Scared the B-Jesus, out of me, AND my wife.

 

[blkblk63ss]

It is ,all thing's I have done did not correct pull. I am tempted to get a global west adjustable upper arm and set the pinion up . I can alway's go back to the original control arm for measurement if needed.

 

[skipxt4]

Do you have a bent axle, or rim?

 

[blkblk63ss]

No,I have corvette rally's and I went through that finding a good set that wasn't bent.....

How about, a broken motor mount, or tranny mount?I know "lame"

All new.no motor jumping or shifter movement..... 4 speed....

 

[blkblk63ss]

I have raised rear slightly i don't know if it is really affecting pinion angle enough or the tracking bar!!!!!
