Another job to do:
The original read diff support D bracket looks as though it has perished. There is clear evidence of the rubber parting company from the steel bracket. Mashtun has kindly lent me his brand new polyflex bush to test and compare against the old D bracket.
The new one is so much neater, and will without doubt reduce the diff wind up. The unknown is will it increase vibration through the chassis?
Removing the tank is the only way to get access to the two bolts which secure the mount to the diff directly.
One other option is to source a new D bracket, and reinforce it with additional hard rubber in the voided area at the bottom. This could ensure soft vibration free general running, whilst helping reduce the degree of diff wind up. However, there is some debate as to whether new Ford D brackets are available?
