Hi all,

My 1984 Lancia beta 2000ie coupe went straight through the MOT last year, but this year it has failed on:

"Shock absorbers (sic) has an excessively worn bush offside rear upper"

Please can anyone point me in the direction of how to find a part/parts to fix this? Is the bush integral to the strut? Or is it a separate bush? Any answers or guidance gratefully received.

Thanks, Mat.

I can only assume that this means the strut top mount, the rubber bush is an integral part of the mounting. They can be found if you search the internet but can be scarce.

It could be the strut worn so the push rod is rocking in the casing. Ideally find a pair of rear struts and new top mounts and re-build them. Early struts have collars that can be unscrewed to change the insert. Beta Boyz parts used to do weld on collars to convert sealed struts to take cartridges.

These can deteriorate badly, but I'm surprised it leaves enough movement for a MOT fail. I'd get the MOT tester to point out exactly what they are unhappy with before buying any parts. I've had two top mounts fail over the years, the symptom on both occasions was that the car would 'shimmy' at the back end when driving in a straight line. With the first one, 30 years ago on an ie, the top of the shocker with the large nut  came completely free of the strut top.

Hi Guys, thanks for the replies - since posting i've done lots of trawling through the internet and found a parts diagram for the rear strut. I still haven't got my head round where there is scope for a deteriorated top bush, I'n guessing it means the large rubber part on top of the spring? Good suggestion to ask the MOT tester to describe what was wrong, trouble is the car is out of MOT now, so I can't take it back until it is booked for another test. So I'll have to just phone them on monday and hope they can remember.

Also not helping is the car lives in storage at the moment while my garage has been knocked down for a new garage / house extension, so it's difficult to get to. As I've done less than about 200 miles since the last MOT, I thought it would be ok, so it's annoying that it has failed.

Cheers, Mat.

The top mount that had 4 captive threads on top and locates the rod of the strut to the top of the strut tower, this has a metal outer then a moulded in rubber bush. The bush had probably detached or become worn/perished

Hi

Thanks mr Rossocorsa for posting the parts diagram, that is useful.

i'll update if i get any progress. I phoned the garage (Halfords) today they said the MOT tester who did mine goes to lots of different garages, they don't know where he is or when he will be back - really helpful.

I won't be in a position to fix the car for a while unless i get a strong steer on what part is needed and am able to find it. Otherwise it is just going to sit on my girlfriends drive. i don't like it being left outside.

Cheers, Mat.

I know that a lot of people on here disagree with me, but I think that a lot of testers fail random things on older cars that they don't really understand. As with this example they have to be nailed down to exactly what is wrong. If the top nut hasn't broken away and the car still handles OK I'd suspect this is a rogue fail, and they would have probably backed down if challenged.

I'd tend to agree. Especially if it's not a classic friendly place.

I had one try to fail mine on beam pattern. It had brand new headlamps. I had to explain that he couldn't fail it on something that was as good as when first supplied.

I would not use halfords as the mechanics will maybe not be tuned in to older cars, I can only assume that the tester thinks something is loose at the top of the strut. This is most likely the top mount unless the strut itself is very badly worn which is unlikely. Try to inspect it yourself if you can.

Yes I don't think I will again ha ha.

I did get a response and they stand by their findings that one side had excessive play. They said it was the upper parts in that diagram "all four parts above the spring". I'm still unable to jack the car to confirm as my tools are sealed up while my garage is rebuilt and the car is a few miles away.

Does anyone know if the struts are common with any FIAT model?

Thanks, Mat.

I don't think they fit anything other than the Beta, the parts above the spring are a thin metal circular ring that the spring seats on, these are often very corroded, above this is a rubber ring which is usually in good order, then the mount itself I think this is the most likely culprit and that the rubber has detached firm the metal outer. The other part shown in the diagram is the bump stop, usually in good order and not relevant to this problem

The most common failure I've seen is that upper mount piece with the four studs sticking out the top. As seen on the diagram here:



Typically the rubber insert starts to degrade and separates from the metal outer and top washer. On the HPE you're able to check it from the top without jacking up the car. I'd guess in the coupe the access might be from the trunk. Usually have to move the carpet off the tower, possibly a tin cover, then you should be able to inspect that top mount and look for signs of separation or just the strut top knocking around in there loose. For a while Mark was redoing them for Betaboyz when you send in your old one. You may want to check that out. Hope you get her sorted and back on the road.

Hi,

Thanks for the post, sadly the car is still in storage while my new garage is being built. It's nearly finished so I'll hopefully get a look at it soon. I'll update once I've had a look at it.
