Default Rear shock bush update

Just de-clunked the XKR.
On this car it cannot be done withouot a spring compressor and a mighty compact one too. Perhaps the XKR suspension is stiffer?
Took off the wheel, lowered the wishbone onto wooden blocks
Removed bush bolt
Not enough room to get at the bush so I compressed the spring another two/three centimetres (if I'd had some sacks of cement I reckon 3 in the boot would have done instead l).
Used a home made tool similar to H2O's but using a 14mm HT bolt and the bush came out quite easily with an air impact wrench.
Used the same system to pull the new bush in.
I removed the rubber boot on the side the pusher was on. Easy to get the boot on but hard to replace the back retaining clip.
Incidentally it is worth taking the boot off - there was the most token amount of grease in quite the wrong place.
If anyone wants engineering drawings of the tool email me.
I can do SW or Autocad.

Very nice job! I remember I climbed under when my replacement bushing came in and said there's no way I'm messing with this on the blocks in the garage.

Is your car lowered by the way? Your 19''s atlases really seem to tuck in with no wheel gap!

How about outputting the drawing to a .pdf and posting?

Here you go.
Mild steel is OK
In addition you'll need an M14 high tensile nut + bolt, 150 mm long plus two or three washers and 14mm nuts with the threads bored out (or larger nuts) to act as spacers when you run out of thread.
I didn't use all-thread because it will strip with the forces involved when using an impact wrench.
This is similar to H2O's tool and,as he says, can be used both to push out the old bush and press in the new one.
Obviously the easiest way to make the catcher is by plugging a bit of suitable pipe. The pusher is out of solid.
It is important to get the holes bored in a lathe so everything is nice and concentric.
Don't go over 50mm OD on the catcher or it will interfere with the strut part of the shocker.


Plums - would it be possible to move these somewhere people can find them ?
My only gripe about this excellent forum is the difficulty of retrieving useful data.

I did this on the ground but, with my 68th birthday just coming up, I'll scrounge the local garage's lift for the other side!
I'm not aware the car's been lowered. It looks a bit further down in the photo than it really is - no idea why!

Tell me about the clunk. I have a clunk in the rear that is small, but hard to find. You hear it most when going slow over small consecutive bumps like a bad parking lot.

Lay along side the car and with your hand gently hold the bottom of the rear shock, then get someone to carefully bounce the car, if you can feel a knocking, you need a new bush.

Yep, that's it. You can feel a clunk with your fingers but no play in the bush. You only hear the clunking when going slowly.

to be fair, the original bush removal tool, I'm almost entirely postive, was XKracer's brain-child, and he first posted his instructions (and I think a sketch) at least once in the historical lower bushing threads. We owe him thanks for this - one of many short cuts and knuckle savers.

You mean this little chestnut , I wont deny I did not dry this up somebody on the XKEC forum did it from the sizes and idea I gave them but basically is exactly what I use, it does get replaced alot, threads strip, parts get damaged, it is one of those tool I have had for years but has had every part replaced many times.

A bit like the infamous broom, I have had it for 20 years and it has only had 3 new handles and 5 new heads

Sorry, credit to the wrong guy!
My only modifications were to work out the dimensions (which I couldn't find) and use a 14 mm bolt which is a good fit in the bush so everything stays square.
The pusher is a lot shorter in my drawings - it only needs to clear the inner parts of the bush.

someone should manufacture that puppy and sell it on TheJagWrangler - Home - About Us (whiteXKR's side biz!) Lots of people would buy one as opposed to building their own.

Good idea, I've asked him.
Seems to me the best idea would be a kit with two new bushes and the tool as well as the tool alone.

I've got the clunk in the trunk and would be interested in the kit with bushes and the tool together.

Did the idea of selling it through the Wrangler's site ever get off the ground?

send a quick PM to WhiteXKR and inquire about it. He's probably going to have to work someone else who will build the tool separately. The bushings you'll have to order from britishparts.uk, as the individual bushings aren't sold in the US any longer.

We couldn't come up with an economical price - a s usual shipping to the US kills making them in Europe.
With the drawings I posted anyone with a lathe could knock these up from scrap in a few minutes though.

I had the same noise and it was the internals of the Left Rear (Cats) Shock, not the Bushing.

I backed up the rear of the car on to a set of oil change ramps and got under it and "Felt" the noise in the top of the shock as a friend shook the rear up and down.

The Jag Dealer replaced both Shocks under the original New Car Warranty that was in effect at the time.

They are talking about the lower shock "bearing". It has to be pressed out and then the new one pressed in according to my mechanic. It is not a bushing.

Thanks, Bill. Didn't know it was a different item.
