P-body 24v updates

[Shadow24V]

inner and outer tie rod ends were replaced with moog parts and falcon(i think) ball joints as well.

as for the alignment, i took it to the family mechanic (good guy and all) and had to get a 4 wheel as the back was apparently all out of whack. he probably did it to factory specs, he was really busy so i didnt ask for anything specific for specs. off throttle it tracks dead true so *shrug*

Shadow,
I was referring to one tire being shorter (OD) than the other. Under load the diff will drive both tires equally, but the shorter tire won't travel as far. This will pull to that side. Higher inflation on the right tire will make it slightly taller, and might stop the pulling.
I am puzzled that it doesn't pull the other way on deceleration. Does the OBX work in reverse? I don't think you need to do a reverse burnout, try ice under one tire.
The Mr. Gasket spreader, #4335, is made out of rubber and won't hurt your spring (your stock left rear). The other is part #1287 and would go under the left rear spring. You wouldn't use both, pick the one that is easy for you to install.
The front coil overs should be adjustable for ride height and you might try that. Mark your starting point so you can undo it if it doesn't help.

It so sounds like it's changing toe when under acceleration excesively, but I could be wrong...

[Ondonti]

if its a serious problem then I think something is out of wack. My OBX behaves properly and I can spin the tires very violently. It goes the direction I steer the wheel.
+ the alignment is totally messed up on my duster and it got worse when I tried to drive forward when a wheel spacer rubbing the brake pad (messed up the alignment) during a racing slicks fiasco that probably 4 TD members witnessed.

Even with horrible alignment (and I think the toe is totally messed up after my wheel spacer issue) the car will go straight if I hold the wheel while smoking the tires.

the guess car - Video

if you skip to about the 1:42 (1:56 remaining) point of that video you can see after wiggling the steering wheel in first gear, I keep the steering wheel absolutely straight in 2nd gear (not even holding the wheel...just laying my hand on top) when I roll into the throttle and then go WOT to spin the tires.

So I dont even have to hold onto the steering wheel. It just goes straight if I guide the wheel straight. Even with horrible alignment.
The steering wheel never once fights me.

I am a believer in the OBX. With open diff...yes the wheel would fight you!
So something weird is going on if you are pulling to the right.

I did my own work replacing the washers and bolts in my OBX. Didnt measure preload. Maybe your OBX is fine..or maybe I got lucky...or maybe you are unlucky with your OBX or tires or suspension.
Ive got enough unlucky that someone else probably will get some too lol.

[Shadow24V]

hmmm, i did do the bellville washers myself so it it possible the stack slipped or something *shrug* it seems tha we can rule out the base suspension alignment due to the fact that deaccel and 0 throttle it goes straight. it is either torquesteer or something else. im probably putting down close to 200whp/tq so... also when i lite up the wheels i dont have to countersteer really, it tends to track straight or where i was pointed...

[Ondonti]

how does it go straight yet pull right?

What do you mean when you say it pulls?

[Shadow24V]

coasting down a hill or on the flat it goes straight, get on the throttle a little and it starts to want to pull right. if you stomp on it it REALLY wants to pull right, it only wants to pull when TPS is greater than like 10%. so if i stomp on it in 3rd to pass someone it wants to pull right, if i let off the throttle while still engaged in 3rd gear, it wants to track straight.

Hey Shadow,
Perhaps the control arm bushings are deflecting under load. It might not be noticeable when the tires are spinning but would show when you had enough traction to deform them.
You changed the tie rod ends how about the control arm bushings?
SpeedyEd

[Shadow24V]

polybushings control arm bushings installed (granted the school's auto shop did it but it LOOKS like they did it right...)

what about if the engine was deflecting in the engine bay due to torque? i have a solid bobble strut but if its not set right (vertical center) or loose a little would that cause something like this?

[87turbodance]

My old '87 Sundance would pull right on the throttle. I later found of stock control arm bushings were destroyed and the alignment went way out of wack under power. Cracked K frame perhaps? Something is changing under load, or like someone else suggested: the tires are mismatched and when the OBX locks the car pulls.

NM: someone beat me to it

[Shadow24V]

when i take the car out today ill see about adding a couple PSI to the right front and see what happens. i doubt that the alignment is wrong as i really trust this mechanic, hes also good enough to call and say "this SHOULD be done, but its your call. thats how i ended up with a 4 wheel alignment. what about deformed tires? the car HAS sat for the last 2+ years on the same tires...

[c2xejk]

I am almost positive you have some kind of suspension problem. It sounds similar to how my wife's van behaved when the tie-rod ends were going... (I would not rule out other suspension problems...) So I would recommend you go over that suspension very carefully including all the wheel bearings... (front and rear)

[Shadow24V]

hmmm, ill take a look at it when i have tools/time. would a bad wheel bearing cause something like that? when im home i may ask my mechanic to take a look at it and see what it is as i dont have a clue at the moment...

[Shadow24V]

well went out for a drive and discovered a few things. the front motor mount bolt is a little loose causing the motor to rock a bit (bout an inch at most i think) and my drivers side axle seal is leaking a bit, not much, but a drip here or there. its damp around the ring that bolts on and the axle input. i may have overfilled the trans, think that might cause it to leak a little? i put new axle seals in when i had the trans out so.... btw its AMSoil MTX oil
