Van Suspension MOT Query

[Jarfar]

Hi,

I have started doing my own mechanical work and enjoying it, including MOT repairs. I have a 2013 Renault Master van and the recent MOT had an advisement of "McPherson strut pin or bush worn but not resulting in excessive movement - offside front top mount". What exactly is this please?

I have googled mcpherson strut, but is the worn part the pin that comes out of the actual damper and the damper needs to be replaced or is it the rubber bush that goes into the strut mount in inner wing?

Thanks

Probably this, you could always ask the MOT tester, I normally do if there is a comment.

I tend to ignore advisories. Over the years I've had loads of advisories which don't get noted on the next MOT.

Export56 - thanks for this. I thought that is what it mean't by top bush. Is the "pin" the rod of the actual damper?

Having been in the trade for 40 plus years I'm at a loss to understand what the tester means. I would probably change the top mount. But if at all possible, go and have a chat with him to find out what it is.

MoT wording has become awfully vague where, for 0.0001% more effort, it could actually be helpful... part of the problem is the tick-box list of phrases, but the examiner can always add his own script...
eg the above, and they commonly use this line for a wishbone, which can have bushes and a 'pin' (by which they mean the shaft of a ball-joint btw)... so which is it?
And on brake discs with 'corrosion, distortion or damage'... well, which one is it?, Mr Examiner You've seen it. You've noted it. You've chosen the tick-box. SO WHICH OF THE ABOVE WILDY DIFFERENT STATES IS IT IN?

[Jarfar]

TwinKam and VintageJock - thanks for replies. Yes I agree on wording being ambiguous. The other MOT advisory concerned the front drivers brake pipe and stated "it was corroded or covered in grease". When I looked quickly myself I could see it was corroded so whats with the "covered in grease"??!!

[TwinKam]

Oh yes, I'd forgotten that howler ...again, commit yourself, which is it then?!
...presumably because someone 'might' cover up a rusty brake pipe with grease?

Thanks everyone appreciated
