Hi people... Im wondering which ball joints/bushes are common fails on the Z? mine has a knocking from the front left.. doesnt seem to be any play anywhere but getting a bit of wheel wobble on braking aswell? any ideas?? Cheers

A quite common one is the tension rod bushing, it is filled with a silicone type oily stuff, have a look for a crack in the rubber and any seepage, quite common to cause wheel shaking when braking too.... Can replace with OEM arm, or press out the old bearing and put in poly ones (most common and cheapest option)....

example of tension rod leakage on mine.............

 

Yeah there sloid mate although i suppose that doesnt mean a great deal when they have force on them.... I will have a better look at them when i get a chance... Cheers Fella

Quick mechanical lesson here if you ever get new bushings pushed in always tighten them with the car on its weight, as if you tighten them up when its off the ground the first bump you hit is too much twist on it and you rip them instantly.

 

you can do it with the wheels off just scissor jack the hub up until it is roughly the right height, you do end up fighting against the shock though so be careful if the car is on stands.
