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.

 

Unlikely, but I did have a clunk once that was the spare tire and jack under the trunk not being tied down.

 

worn rubber. panhard bar banging around. spare tire... there's also your evap cannister under the rear spare tire bulge... that could be loose...who knows... Shocks not fully tightened..
A shop can put it on a lift and use a pry bar to look for play in the parts.

 

Thank you for the replies, I tightened the 2 bolts on each side of the rear sway bar.
While looking around, I noticed something abnormal and took a couple photos. Both sides are displaying this.

What is this?
