Re: How to test suspension? 156 SW
ARB drop links are the most common problem, with the car jacked up and wheel removed give the drop link a wiggle to see if there is play at the bottom or top.
second most common problem is the wishbone bushes, there are upper and lower wishbones, checking for play in them requires you to use the crowbar method with car jacked up and wheel still on. rock the wheel using the crowbar between floor and wheel, then you can inspect the bushes on the wishbones for play.
if in doubt get to an MOT tester, it'll take them 30secs to identify it once its on the ramp. if you aks nicely when they arent busy most places will have a look for free.
