TR4A : UPRATED REAR UJ DRIVESHAFTS

£500 (pair)

Engineering Improvement to Classic Cars

Installation

Please refer to a good workshop manual to do this task.
Removing the shaft with the hub is relatively straight forward.
Thoroughly check the 6 studs on each trailing arm; they are known to be a ‘weak point’ and vulnerable to ‘pulling out’. Our 3/8 unc hub stud kit solves this problem !
When replacing, the 5/16 nylocs are torqued to 18 lbs ft
NB: Stag ‘staked’ universal joints cannot be changed.
Removing and refitting the outer UJ is a bit of a black art so to be honest it is better left to a specialist.
Whoever does the job when it comes to reinstalling the shafts make sure that they are aligned as show in the picture below.
The joints and spline are already greased but you can add a little more, do not over fill.

It is also good idea to spray them with ACF 50'' to keep them looking A1 and to
protect them against corrosion.
