Hi

2003 mach1, 80,000km, no suspension work other than it being lowered 10+ yrs ago.

I've had an annoying clunk present over certain bumps around 20-30km/h.
Always a single clunk, never more.
I believe it is the passenger side.

My next project would be how the car pulls to the right when accelerating (new tires) maybe left tie rod, maybe related to the clunk so thats why im mentioning it.

Yup, if that is the rubber from the bushing eroding out and not just road crud, you've found the likely issue. I replaced mine with Maximum Motorsports HD LCAs...these have a urethane bushing on the chassis side and a spherical bearing at the axle...great mod. Consider replacing the uppers with new rubber bushings at the same time (I did while I was down there). Both are worthwhile corrective/performance mods.

Btw, read the info on the Maximum Motorsports website as to the "why" of retaining rubber bushings in the uppers...explains it better than I can, but in a nutshell it prevents binding of the suspension and torque box damage.

It brings a sense of accomplishment knowing it was the right decision :) Thanks for your help along the way.
Clunk is gone.
