HELP ME!!!!!! 1999 Bonneville SE (Steer/Brake issue) !!!

Post by bigmandev92 »

Problem: Steering feels loose......when stopping steering wheel dips to the right..and when releasing brake pedal feels as if the driver side caliper releases late. The wheel straightens up after the rotor breaks free. (O_o)

Replaced Both front calipers............Driver side brake hose.......Stablizer links..

Help me please!!!

(Also noticed I need to replace a few mounts mainly transmission ones and the torque strut mount, drive train did alot of moving when jacked up and in drive)

Have a look at the bushings on both control arms. A second person needs to turn the wheel back and forth at each of the 100% left and 100% right as you inspect each respective control arm.

Next would be the same exercise for the ball joints. You are looking for any loosness in the bushings, and any non-rotation movement in the ball joints.

Forgot to also mention 1 bolt on passenger side balljoint has broken and disappeared 2-3 times since I've had the car any idea why?

Check the cradle bolts / bushings to make sure they are still in good condition as it is common for them to rot away over the years and that would certainly cause some steering issues.

Other then that, I agree to check the control arm bushings and ball joints.

I sure will check all the things you guys reccommend here thanx!
Will control arm, balljoints cause the "sticking brake" feel also?

Both can give a bit of a clunk after you hit the gas, so kinda. I guess we'd need a better description of what the brake sticking you're feeling is.

Also, if the ball joint is missing a bolt, and you've tried replacing it with anything other than class 12.9 (for metric) or grade 8+ (for standard) then it will only just keep breaking. At that point, I would just replace the ball joint again with a quality new part. Like Moog (check out rockauto.com).

Checked out all the things you guys reccommened and everything looked to be okay, I picked up the correct bolt and put it in. Went to go somewhere thinking the problem would still be there but NOPE that one bolt solved the problem no dipping steering wheel when braking no sticking brake feel either! Thank you guys
