Hi,
I have been following this thread with interest, as I have replaced both rear wheel bearings on my motor.
You are all right, in that this is not a job to undertake lightly, and you need to understand how the drive hub, drive shaft and bearing are fitted together, and plan how and what gear you will need.
Before I did mine, I enquired at local Vx dealer. They were quite straigtforward. The car was just not worth it. Yes, they probably knew just what a job it was, but with the proper Vx tools and post lift, I doubt the job would take more than an hour. So I guess they didn't have the gear.
I approached three small local garages, the cheapest I could get was £400 and only one admitted they had previously done the same job. Their's was the dearest.
The alternatives are, Remove the suspension arm complete, and take to an engineering workshop with a press and various mandrels and ask them to do the job.
Removing the arm and replacing is not just a simple job.
I decided to study just how the Vx special tool works, and to mimic as best I could with what junk I had accumulated over 50 years car DIY and Motorjumbles.
Provided that it is not a "horror job" where the bearing is fretted and siezed into the suspension arm, the following Heath Robinson gear will enable you to change the bearing.
1- Two legged bearing puller to remove the inner drive shaft hub.
2- 32mm socket to undo the drive hub nut.
3- 2 off 10mm X 100mm set bolts with nuts and washers, to remove the wheel drive flange and shaft.
4- Piece of 3" steel water pipe 2" long as spacer to pull the bearing into.
5- Piece of 12mm studding 9" long with nuts and some big thick washers to use as strongbacks. I used the long jack screw from a bearing puller and an old front wheel hub as a spacer.
6- You can use the old bearing as the spacer to pull the new bearing back in.
The above gear will remove the bearing and pull in the new bearing without any possible damage to the suspension arm, or the new bearing.
If anyone wants greater detail of how to do it, then PM me.
I am happy to lend any member the gear I have put together to do this job, with instructions, but it is all very heavy, and goodness knows what the post would be.
