Default Suspension is a disaster again. Need advise on parts

A while back I had the sway bar bushings, the front control arms and the rotors all changed. My car was quiet for a little bit, but clunking came name pretty soon. At this point, about a year later, I've degraded back to terrible clunking and vibrating at stops plus rear end feels really wobbly. The suspension with this car is a never ending nightmare.

I am assuming that whatever aftermarket front rotors my shop used have probably warped and that's part of the vibration and clunking. The additional front end looseness I have no idea. The wobbly back is probably the rear control arms.

I am assuming that the aftermarket parts for this car are all trash.

What kind of rotors should I buy? suspension parts?

Any help is greatly appreciated

I actually got these for my X 2 years ago and they are still going strong.

Mark: Have you checked the sway bar links, front and back?

Jaguar x Type Sway Bar Link New Fits 2002 2004 | eBay

Jaguar Sway Bar Link C2S39552 | eBay

As they age, the ball joints in the link can loosen ever so slightly and this small amount of play gets amplified into an annoying "tap, tap, tap" sound by the sway bars whenever you go over bumps or apply the brakes. It's as if the sway bars become large tuning forks that amplify the sound of minor play in the sway bar links.

To test this, put the car on ramps, lie under it on your back, hold the end of the sway bar near the linkage with one hand, and push the car up and down with both arms. No need to be Arnold Schwarzenegger; just ~1/4 inch up and down motion is enough to feel and hear any play in the sway bar linkages.

If you hear noise when pushing the car from beneath, but your hands don't feel the noise coming from the sway bar ends, then repeat the process with other suspension members to see if you can isolate it.

On the front-end, the strut mounts, when old, can also generate a cluck sound over bumps. Open the hood, place one hand on the top of the strut tower, and have a friend bounce that corner of the car up and down. You should not feel a clunk if the strut mounts are good.

I forgot to mention the sway bar links have been done as well.

Mark: PM me if you'd like another set of eyes to look at your suspension & brakes. I'm in west Houston. Sometimes two heads can troubleshoot better than one.

Thanks for this, you just answered a question I was going to ask. Just had a new wheel bearing hub fitted after the shocks/dampers and I still have a clucking noise in rear passenger side when going over the smallest bump in the road.

Suggestion: Check the round rubber weights attached to the rear brake calipers, #10 / #11 in this diagram.

If the mounting bolts loosen, the weights bounce against the caliper, and every bump in the road creates a clunk noise I mistakenly thought was a loose suspension bushing.

Two solutions: tighten the mounting bolts, or remove the weights.

Thanks for all your replies. I tried sending you a PM but you seem to have that function blocked :-(
