Need help diagnosing suspension clunk and steering wobble
Hi all, this is my first post in the group. i usually just read others posts but this time i have not been able to find anything relating to my problem on any of the forums.
I have a 2000 2.7L boxster 986 and for awhile i have had a dull clunk only on occasion from the front drivers side wheel area. However over the last month or so it has been getting worse and worse. it clunks over any bump or even if the asphalt is slightly irregular if i hit it a certain way. it may not do it over bigger bumps if i go slowly.
from what I have read a clunk could be anything like a strut or strut bearing, wishbone, control arm, tie rod ends, wheel bearing etc.
however now that the clunk has got worse im realizing that it is effecting the steering of the car. when i go over bumps the car steering wheel shakes back and forth a bit and i have to fight it a little. and on the highway the steering also slightly vibrates and every time i hit a bump with the driver side wheel it clunk and the steering shakes. If i hit a bump with the passenger side front wheel the car is fine.
Ive jacked up the car and given it a good shake down and found that when i turn the steering wheel, both wheels move the same amount and when i move the wheels the steering turns the same amount. no clunks. so i dont believe its a tie rod or steering issue. also the car turns fine on the road. it just gets squirlley when i hit a bump.
I've been trying to inspect the wishbone and control arm and drop links but don't find any cracks or tears in the boots/bushings. and i cannot find any play with the suspension loaded or unloaded. but maybe im not doing right?
I've inspected the upper strut mounts and they seem to be good and bushing is still there, maybe half inch of solid bushing.
I also shook the wheel at 12 and 6 and found no play so im assuming the wheel bearing is fine. there is also no road noise when just driving along. only when i hit a bump and only when i hit a bump a certain way.
Also; when i jump up and down in the trunk or push on the fender side to side or up and down i cant get any noise at all because of this im leaning more towards the tuning fork/control arm. track arm or whatever it is called forward most control arm.
any help would be really appreciated! Im leaning towards the ball joint on the wishbone or the ball joint on the control arm but not sure which would cause this issue.
