4 wheel tracking not possible on a Rover 75

[loz1971]

As there is no adjustment point on the rear suspension

This is what I have just been told by my local tyre fitter, he is new to 4 wheel aliment but was convinced.

So I told him it is possible and has been done by several members on here, so now he thinks there is something that he wasn't told whilst being trained, so can anybody explain how the adjustment is done, so that I can tell him and get it done on my car please??

I'm sure he still doesn't believe me and that is why he asked me to find out how it's done

I know for a fact that 4 wheel tracking is on the tourer because I've had it done. As for saloons I'll pass on that.

Another GY owner, keep your eye out for BRG tourer on grey and chrome alloys, private plate...

still seem to be plenty around here but went to Scunny the other day and it seems to be the 75 & ZT centre of the universe! saw god knows how many 75s and at least 6 ZT in a matter of 30mins.
My ZT boring X power grey with rear tints and tatty alloys not the best I should have searched longer. It is still nice but easier for you to watch out for our celestial blue TF instead!!

Thanks for that mate, now I wonder what this special tool is?? is it really necessary or can something else be used?? I don't want him saying he still can't do it because he hasn't got the right tools!

from the picture it looks like some sort of off centre socket ?? not sure but i'm guessing it's not that important

The mounting for the radius/trailing arm has slotted bolt holes on the mounting plate and there are some lugs on the nearby bodywork. The adjuster tool has a 'hook' that fits into a lug. This allows you to apply purchase to the mounting plate and slide it under the bolts. Moving the plate in/out alters the rear wheel toe. I've adjusted mine myself using a Gunson Trakrite shear gauge to get perfect toe.

And I take it this applies to all models, and not just the later ones, as mine is a 2000 W model
