Rear wishbone bearings

[Warren]

At this rate I will have more replacement parts than the Cobra but after more surgery I am back

Reassembly of suspension going OK till I got to the rear hubs.

Rear outer wishbone bearings preload. Various ways are described but most require you to torque up the outer shaft assembly with shims etc in place to 95lb/ft. Every time you elimate the play but take it apart and the shims are completely knackered, split. Can someone explain how to do this in 'idiot speak' so I can't go wrong.

Next question, same bearings. You fit the new bearings and then a thin spacer ring, in goes the felt seal followed by the seal retainer. Is that it, or is there some other washer that fills the space between the retainer and wishbone. I have searched high and low in the garage but have nothing of the right size. There must be something other wise where do the outer shims rest.

Does anyone have a good diagram, better than the manual or a photo of the component parts.

Cheers
Warren

Hi warren

I have all the diagrams you need but they are to big to post here,
give me your E:Mail address and i will send them to you.
I also have the original jaguar workshop manual volumes 1-5 on cd, i can do a copy and post it to you, but this will obviously take longer.

I have bought a haynes but cannot see the detail. As for the workshop manuals, that would be great. Send your address and I will send you a CD.

Thanks

This might help, if you can see the part numbers ring John Gordon and he will advise as to what you are short, if any. Tel 01254 398476

Warren,

I think the felt seal needs to sit in the 'L' of the retainer, this should sort out the "space between the retainer and wishbone" issue.

Warren,

On your first question, here's a quote from the Kirby Palm book:

"The ROM recommends tightening the trial assembly to 97-107 ft-lb, and the Haynes recommends 95 ft-lb. Basically, this is final assembly torque. Here, I will differ with the official recommendations and suggest you do not tighten the trial assembly that much; go to 40-50 ft-lb only. Here’s the reason: at trial assembly, you will be turning the two nuts against each other, and somewhere in the stack between them there must be slippage. This slippage will probably occur at the shims. In achieving full assembly torque, the thin shims may decide they’ve had enough and get ripped out of the stack forcefully by the shear loads. This isn’t a problem at final assembly, because the ends of the swingarm fork are involved; they positively prevent any twisting within the stack, and force the nuts to slip on the swingarm fork faces as they are tightened. The shims won’t be harmed by pure compression."

Thanks to all, the last bit makes absolute sense and I can see that working.

I could feel a little end float with 4 or 5 shims at lower torque levels so this sounds about right.

As suggested I will take the lot up to Johns and see what is missing.

Cheers

Mike's message above states to ring John Gordons. I would also recommend this course of action. They know exactly what you want. Speak to Les, he has all the part numbers in his head. Also they have exploded diagrams that they will either fax to you or send you in the post. Most helpful. They were a god send when I was doing mine.

Hi Warren (I met you at JG's),

I had exactly the same problem last week-end, got a selection of shims etc all ready to go.........what a mess!! shims totally u/s.
Fortunatly I found a copy of the Jaguar World Monthly which states in a build up article of r/suspension etc torque to 55lb/ft not 95!!. x(

One other thing I would look at before you reasemble are the spacer tube or tubes as after going to 95lb/ft as stated in Haynes my spacer tube ends have "rounded off" slightly so I can't trust them not to screw the shims out again so I will re-new them at the same time.

Ah well get it right next time.

Regards Shane

Hi Shane

How's it going. Once again this makes sense to me, its amazing how you can have a reasonable engineering understanding of what is going on but still trust the black and white of the haynes.

Drop me line and let me know how you are getting along. I have been a bit hampered recently, the other end of the bone that needed the hip replacement gave way and I have had surgery to remove the fragment. I'll be the bionic bloody yorkshire man at this rate.
