Rear shock bush update

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.

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'm not aware the car's been lowered. It looks a bit further down in the photo than it really is - no idea why!

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

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.

Seems to me the best idea would be a kit with two new bushes and the tool as well as the tool alone.

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.
