Thump/Rattle from front over bumps.
I am looking for someone that possibly has experienced this concern and could provide me a fix for this issue. My car is a 1994 3.8L LX T-bird, with 156000 miles. Recently , (within the last 3 months), when hitting several bumps in succession I get a repetitive "heavy" sounding thumping/rattling from what seems to be the steering gear area of my car. In other words, it appears to come from the center of the car, just under the engine.
I have replaced the struts and their upper mounts, the bushings on both ends of the strut rod that attaches the lower control arm to the subframe, the sway bar links, both upper control arms, both motor mounts. Stepping on the brake when the noise is present makes no difference. The lower control arm inner bushings, (the ones used to adjust the alignment), and the rack bushings look very good. There is no shimmy in the steering wheel at any time, so that proves out the rack and lower arm bushings. I have also removed the air intake silencer and verified the carbon cannister is not loose.
TCCoA members, any thoughts??? Please advise, Thanks in advance.
