Restoration Of Chassis Diff Mounts.

[ceejay]

The original rubber Diff bushes and the lower torque rod bushes which remain hidden from view, will, over the years perish & rot away due to oil contamination. (And allow the diff to move around). The photographs below illustrate how the original diff mounts can be restored to better than new.

The old rubber is removed from the shells, the bushing material (Red Lurethane) can be purchased in rod form and machined in a lathe as shown, the two machined halves are secured into the metal shells with Loctite 596 RTV.

These photographs were taken back in 1983 during the rebuild & restoration of my elan S2. The lower diff torque rod bushings were treated in a similar fashion, on recent inspection, the bushings are as good as the day they were installed.

I believe it is important to use the lurethane on the chassis diff mounts as well as the lower torque rod bushings.

The Lurethane can also be purchased as a pouring kit if you want to go that route, but I found that machining was far quicker.

Do you need a metal sleeve in the rebuilt mountings for the bolt to tighten against

The photographs were taken before the bushes were completed, the sleeve acts as a pre-load control meaning you cant over tighten the bush which may cause the rubber bush to squish out sideways, the lurethane wont do that.
