glht Serious issue 1 of 2! HELP! (Susp)

[dart165]

I bought an 85 glh-t and i'm trying to get it ready to become my daily driver because my lease is up soon, but i'm having some real issues, that need addressed ASAP.

look for my other post as well if you are in a super helpful mood!

ISSUE # 1: When you are steering straight or to the left, its as smooth a ride as can be. The moment you steer to the right (at all) i can feel a grinding, and vibration. Further more, it appears that my caliper bracket it hitting my rotor and tearign it up. The car has a new wheel bearing on that side, and new axles, but i'm at a loss, could it be the strut mounts?

Ask me questions if more info is needed, and i'll answer to the best of my abilities (i'll throw some pics of the rotor damage and anything else i find relavent up later)

I appreciate the help! thanks

Sounds like you got a bad aftermarket wheel bearing.

Correct me if I am wrong but 85 does not use a hub bearing assembly.
The hub and bearing are pressed into the steering knuckle.
If this is the case either the bearing/hub was not pressed properly or the hub is bent.

[dart165]

i'm pretty sure it's not the wheel bearing or a bent hub becasue the issue was there before i had the wheel bearing done. infact thats why replaced the wheels bearing/hub. All things pointed to a bad wheel bearing being the reason there was any play and that the rotor was rubbing. That's why i'm so dam confused now!

One other thing i forgot to mention that i did notice, is that that front pass wheel has a positive camber to it, (i beleive it's positive.. it looks opposite of what it should) even after i adjusted the knuckle to its most neg setting... wtf?

[NAJ]

To check the hub you need a dial indicator and you check runout.
No more than .001".
As far as the wheel unless you see something obvious it needs to go on an alignment rack to see just how far it is off but camber will not cause the rotor to rub since the whole strut, steering knuckle, hub and brake assembly move as one unit.

[zips11]

which part of the rotor is grinding? pics? camber is visibly out? thats a lot.

Wheel bearing.... I replace these things so often that I bought a press last weekend and I have a chewed up rotor to prove it. Never mind the fact that I "cleaned up" the brake caliper to prevent the rubbing when I was in denial about the bad wheel bearing. I push the bearings a little harder than most and they are the cheapies. Probably going to go with good ones (expensive) this time, but then why do I need the press? Oh well, I'm sure there's other uses to be found. Harbor freight has a great kit for pulling the bearing sleeve without removing the knuckle!

If its not the bearing or a bad install then it has to be a bent hub/knuckle.

[dart165]

ok. i FINALLY got to take a look at it tonight, and it looks like the caliper mounting bracket is hitting the rotor. This, combined with the positive camber of the wheel makes me think the hub is bent... Here's some pics

AARRGGGHH!

-i replaced the wheel bearing... no dice.
-replaced the hub & the bracket holding the caliper -still shaking
-replaced the strut assembly figuring it could be a bad strut bearing -still bad!

WTF!!? Could the motor being off center have any effect on it?
I guess i have to take the car to a alignment place and see what they say, or to a frame shop and see if they can make sure its straight because i am out of ideas here!

Anyone have any suggestions???

[Gutfeeling]

Are you sure the bolts for the caliper bracket aren't bent?
Missing a spacer between the mounting points of brackets?

no

you said it was doing this before the wheel bearing swap... its possible the rotor(s) you have (they look new too?) have been improperly machined

possibly swap them L to R and see if the problem moves to the other side

I dont recall any "spacers" between caliper and hub on the GLH/SC

I have some SC spares, everything BUT the hubs IIRC, I would have to check to see what I got ; do you have your old stuff ? swap an old rotor on there and see if it looks centered ILO offset ??

[dart165]

I replaced the caliper bracket bolts when i swapped the caliper bracket, so i don't think it's that.

As far as the rotors go, they are new. The old ones were chewed up the same way though: The dr side was fine, and the pass side had excessive wear on the outter edge.

i hate to sound inexperienced... but what is a ILO offset?

[Travis_k]

It looks to me like the caliper bracket is bent. Get a new one and try it. If the wheel isnt loose if you jack the car up and try to move it, the only things it could be are rotor hhas something wrong with it, bent hub, or bent caliper bracket.
