Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Noise from rear

Hmm, later cars are obviously a bit different to the 70s ones structurally.

In the 70s, the prop shaft cover was steel and welded to the gearbox cover. The rear part of the metal-work is only screwed to the rear woodwork so not only exists the possibility of the wood cut out being fouled, but of the metal work being to one side and the prop hitting that.

The prop hitting the wood sounds like wood being attacked, and I'd suspect if the prop was hitting the cover, a metalic sound would result.

It's all pretty basis stuff, you just need to remember the springs move sideways quite a lot at the axle so the analysis of what is hitting what ought not be too difficult. I suggest you don't hurry here, and even the act of explaining and showing the problem to another will probably help.

I've never asked a dealer about this, but they must be pretty familiar with the problem and cures.

The cutout on the rear panel of the later cars is quite large and a flared alloy casting fits onto it from the alloy tunnel cover so it would need a fair amount of axle displacement for the prop shaft to catch. The panel itself is cut using a template so unlikely that the cutout was incorrectly done.

I don't know what year Cats car is so of course the above may not be appropriate!

I have a thick rubber stuck with super glue to the diff it stopped it .

Just a late contribution to this topic.....

In standard form, the rear axles in Morgans move around a lot when cornering. In some cases, the leaf spring and the spring-to-axle mounting plate will come into contact with the inside of the chassis. It can also be exacerbated by the axle being slightly offset - Morgan's are hand-built after all! The extra weight of a passenger will only make matters worse.

Use a torch and shine it down along the inside of the chassis; you should see any signs of contact.

As per the advice from previous contributors,a panhard rod is a useful enhancement and will improve cornering. No longer will you feel the car 'lurch' into the corner following the initial turn-in. I bought one from Dave Rutherford in the early eighties and never looked back.
