I stripped the passenger side suspension today and found the following

Disc worn in an offset way
Wheel bearing noisy when spun
Play in the trailing arm bush nearest engine.

I've never driven this car but I can tell the above is not good!

Can someone help me with which part numbers I should be ordering and which part fits next to engine and which fits on fender side?

It's a stock road car so no desire for poly bushes.

I believe you are describing the bushings in the assembly #1

Yes they are the ones. Might as well change both while the arm is off. The link is removed from first post as it went to a merc!

Not a problem, Pelican is a reputable vendor

I'll come back to you tomorrow once I've removed the arm.
