Suspension refresh D3 4.2 tdi

[Alex C]

Hi all and happy new year.

My car is now approaching 100K so I am thinking about refreshing the suspension. Air suspension seems fine and holds height OK so its more the bushes etc that I was looking to renew.

The car is pulling to the left, initially a small amount but now noticeably worse in the last month. ARB links are new TRW (after Meyle disintegrated after 10K miles ) my thoughts are the track control arms are the culprit.

As the car feels just a little baggy now I thought I my as well have tracking done on new arms rather than trying to rectify this on the factory fitted parts, but then wondered if I should bite the expensive bullet and do everything in one job.

Is there a definitive list of parts anywhere? From searching I found a few threads where only certain elements were done.
I noticed this kit but was assuming quality was probably a bit iffy?

Would a match of these elements in TRW parts be OEM quality or are some other bushes needed?

Thanks.
