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....

 

Check the Big nuts that hold the spindles and shocks together.(17mm,I think)
Pull the wheel off and check that area for play.
If the shock moves,In and out,then you haven't tightened up the bolts enough.That would make the car want to Go In another direction,Like what you are Saying.
Also,you can check the wheel play Before you Take the wheels off.Check for loose Ties rods,ball joints,Bearings.
The "alignment check" should have actually Picked up any Flaws in your Steering Dilemma.if you find anything,don't bring your car to them again.

 

Did they put it on the alignment rack and give you a print out?Have your tires been wearing out on the inside

 

sounds like one of the links in the rear suspension is worn (probably the lateral links)

jack up the car and look to see if anything is loose or looks like it's in rough shape.

it could also be the DTSS bushing are bad.

 

yes they put it on the allignment rack and gave me a print out... but the circled the rear caster? and wrote not adjustable next to it? i donno. and for the rest im going to give them a shot and get back to you guys... thanks alot for the help

 

my 2 cents.

I had the same problem. I had a bulge on the inside side wall of the tire, that I wasn't aware of. It blew out 1 day later. I replace tire and problem was fixed ...
