HARD PULL TO THE RIGHT... Need Help!
 

So my 89 fc going straight needs constant effort turning the wheel left in order to go straight... i got an alignment check done and they told me the rear passenger side wheel was off with camber and caster. the camber is a givin with the drop. (kyb shocks w/ rs-r springs) But I wasn't aware that caster could effect steering? and they also told me that nothing back there is adjustable and need to bring it to a place that specializes in suspension. I'm hoping that with new coilovers i will be able to fine tune the adjustments myself and make it right. but i dont know what coilovers to get yet and am looking for some suggestions to maybe help me out for the time being... thanks alot guys for any help... its greatly appreciated....

Caster in the rear wouldn't affect the steering in the front, it would be rear toe that throws off the drive line axis and possible it's something in the front thats messing with it as well. Has anything been bent or worn out bushings? I'll check out the alignment machine at work and get back to you on this.

First couple of basic things to do.

1) check you front right caliper to make sure it is not sticking. Pull the wheel off and inspect the pads then spin the rotor while the wheel is off and make sure that it spins and does not just move a couple of inches then stop.

2) While you are there rotate the right side tires to make sure that you do not have a separated cord on the front tire.

i will try this and let you know what happens... thanks i need something to fix this ha

"Caster" doesn't exist on the rear end, to measure caster you turn the wheels in and then out 20 degrees to get your number so that would be pretty impossible on anything that isn't a front end.

Things to check/have checked:
1) Tire pressure!
2) Lower caster angle on the right side than on the left. (You should have 0.5 to 1 degree higher on the right side)
3) Worn/uneven tread on either front tire.
4) Sticking caliper (as mentioned above)
5) Extreme amount of toe in/out or extreme amount of mismatched camber.

my rear wheels both seemed to be toed a lil bit and im ot sure how to fix that with the set up i have.. kyb shocks with rsr springs... nothing seems to adjustable.. kinda lost in what i need to do to fix this problem...

I haven't been under an FC in a while, but I'm pretty sure the stock rear suspension has toe-links that are adjustable.

if so that would be awesome... ive heard they dont but tomorrow morning we will find out...

The rears do have OEM toe adjustments and also the computer only told me the tool used for camber in the rear is a camber gauge, guess the rear only has that toe adjustment.

The rear will also have a camber adjustment, a cam-bolt with an offset lobe that will look like this:

Should be located where the lower control arm meets and bolts into the rear sub-frame.

A camber gauge won't adjust your camber, only measure it. And remember, toe will ALWAYS need to be fixed after making an adjustment to camber. It's just a universal rule of the alignment world.

Differetial tire pressure (side-to-side) is typically the issue when you encounter a pull. Extreme caster differential would be the next issue to consider.

the most common thing with a hard pull like that could be a slipped belt or an actual belt seperation. Just cross the front tires and if it pulls the opposite direction then you found your problem. Also if you could post up some numbers from your alignment it would be a simple diagnosis.
