suspension walk

Postby tsoob » Mon Dec 27, 2010 7:09 pm

I cant seem to work this out with my car:

It has a heavy duty sway bar and lowered springs, for some reason it has a horrible 'walk' or left to right pull, it seems to be when you come on or off the boost but the car rocks sideways..

Im wondering if the shocks are now poked but wanted to run this past some of the guys on here.. Thoughts please boys :)

Shocks would have been my pick as well.

If it goes one way when accelerating and the other way when braking it could be a worn drive flange in one of the front hubs . The back bearing wears on the flange and allows movement so the car toes in or out depending on accel or deccel , easiest way to check is remove the wheel undo the CV nut and try to pull the flange out by hand. I had 2 or 3 of these on the starlet before I figured out how to loctite the bearing races on :lol: .
Or it could be what the others have suggested , thou I think BHG is less likely :lol: 8O

"Understeer" is when you hit the fence with the front of the car.
"Oversteer" is when you hit the fence with the rear of the car.
"Horsepower" is how fast you hit the fence.
"Torque" is how far you take the fence with you.

Hahah!

When you feel it pull, where do you feel it first, like in the chassis or through the wheel?

If it steers across the road without pulling the steering wheel it won't be torque steer. I drove 4WD car briefly that did this, I assumed it was a diff fault.
Variable toe sounds possible too though, has everything suspension & steering related been checked for wear/play?

Torque steer... possible, but I have a very very tight lsd, it just hooks up and goes.. and this has just started happening lately, and its getting worse.

Shocks, my first thought, and i'm sure i have a spare pair at the shop so ill try those and see how it goes.

Wheel alignment is pretty good was done around 5k's ago, ill try a recheck once i have done the shocks.

I have rebuilt all the cv shafts, i do need to do the wheel bearings and will also do ball joints and tie rod ends, BUT i want to wait until i do the brake upgrade.

Where do these flanges you speak of go??

by drive flanges I think he means hubs

What are your bushes like? My AW11 used to steer under left under drive and right under overrun because the bushes would let the arms move around and change toe, easily fixed with a set of urethane bushes.

I'm not at all familiar with a Corolla's suspension, but if all the bushes in your arms are urethane then that's unlikely to be the issue.

Unless they weren't lubed correctly and they could be flogged out. Happens real fast.

And check the back end as well as the front. Flogged rear bushes could cause "realignment" under acceleration too.
See ya

Drive flange is the thing that has the wheel studs in and the spline for the CV to go thru. It goes inside the wheel bearings in the hub.

Mine did a similar thing not long ago, turned out to be the fact that i had a new tyre on one side and a half worn one on the other, caused a pretty big walk to one side under acceleration like you describe. Changed tyres around so it was even and it was instantly gone.

The part you call a drive flange is more correctly known as a hub. The part you call a hub has about a billion different names, but upright or steering knuckle are some of the more common ones
