My new 75 failed its mot on the nearside arm, the tester said he's surprised the spring hadn't gone through it was that corroded! Its being sorted tomorrow hopefully, then getting retested in the week.
I'd have a go at changing it myself but it looks an absolute pig to change, and you need to have it on the ground to tighten up the bolts! There's absolutely no chance of me fitting under the car while its on the ground! I only just fit if its on axle stands!
