Steering UJ wrongly phased Coupe

Post by roymck » Thu Feb 21, 2019 3:48 pm

The upper UJ on my column was siezed so ordered a new one from QRG . It’s wrong as it’s impossible to set the UJ correctly in line

with the lower UJ .
The UJ on the bottom end on the rack is one piece with the lower shaft , so you can only fit the upper UJ in line with the cut outs in the column and it’s totally wrong . Anybody else came across this as it’s bad engineering practice and I am not happy.

Can't see the issue, both ends are splined.

The issue is the bolt will only pass through with it in one orientation?

Been a while since I stared at the column UJs and splines but don't some parts have a groove all the way round and others just a slot (so fixing the rotary position)?

On the old joint the bolts runs in line with the UJ , on the new joint the bolt is at 90 Dgs to the UJ. So if you assemble it up one joint would be horizontal while one was vertical . This will make the steering notchy !

The rack has a cut out all the way round so the lower joint fits on in any orientation . It is a sold forging with the shaft . The top of the lower shaft has a notch and the column has a notch as well . So both joints need to be inline or the shaft will rum out of true . Think of it like a propshaft the UJ,s have to run phases together . 2 ways round it cut a groove round the top of the lower column and spin the joint round or get the correct UJ . The pressed steel kind is listed on Car Builder Solutions .

Anybody else seen this problem ?

Run a drill through it or file - not that difficult to modify.

There are obviously 2 types of joint as seen on my first picture , both are available from Car Builders solutions so could have ordered the correct part from them if I had known .

I understand phasing, but I can't see why you can't get it right by adjusting it on the splines. If it is 90 degrees out, then position one end 90 degrees out. Easier than getting it swapped out.

Because the bolt will only go through in one position, which will mean modifying the shaft.
