When you say steering arms are they the wishbones? Just changed both rear wishbone bushes and it corrected the pulling to the left i was experiencing. Totally transformed the handling of the car. Feels like its on rails now.

Hi Jonathan,

How did you know those bushes were shot?

Sorry i didn't reply sooner, I joined this forum to sort out my mums car and help others with my findings. The forum I use for my car emails me when someone responds so thought i'd been ignored on multiple posts!! This one appears not to email you, i shall investigate lol.

If you cant get it on a ramp then jack up the car and axle stand it. then when you look at the wishbone there are 2 ball joints and one large rubber bush at the rear. On my mums what i found was that i could hold the wishbone in my hand and move it easily without the use of a pry bar on that bush. it should be solid and only move minutely with a pry bar on it. How it ever passed an MOT i have no idea. It was dangerous. I had the tracking checked as thought it was that, then whilst on the ramp i went under and had a prod and poke and realised how bad they were. Changed them both and the car is transformed, as i said before, its on rails

I used EuroCarParts. Just put the reg in, they come in pairs Product Code: 618110298. enter voucher code midmonth20 and it comes out at £42.39. Make sure yours are bad before you replace them. As i said, these were completely destroyed.
