I've changed the bottom coupling before, but was not expecting the top one to be such a PITA. However, with the bottom joint and rod out, the supplied part is about 10 mil longer. I called Geary who honestly said he'd sold many, but did not know if any had gone to a VX.
Should not be a problem. There's enough play/slide in the system to align everything.
Also the supplied top joint has a larger opening than the splines on the other end and those on the bottom UJ?
The upper steering column is not splined like the rod and steering rack. It only has a flat side on it, so the upper UJ has 2 different 'sides'
To replace the upper UJ and keep your sanity you should really remove the steering column. (remove dash, remove stack, undo bolts, lift out)
I have never been able to undo the upper UJ connection to the steering column with it in place.
Do NOT 'spin' the steering wheel when the shaft to the rack is disconnected! The airbag and horn use a clock-spring mechanism which only allows a certain number of turns each way.
With the steering column removed from the car, undo and remove the upper UJ, attach the new one and tighten the bolt onto the upper column, attach the intermediate shaft (just insert the bolts so it can't fall out, don't tighten yet) and feed it back into the hole and connect it to the steering rack.
Now 'shuffle' the UJ's and connection so they all align and tighten down properly on all remaining (3) bolts.
Remove the steering wheel and re-set so it sits flat when going straight. You may need a re-alignment if 'straight' is just either side of a spline.
Job done!
Bye, Arno.
