I blody hope so Naki :lol:

Anyway, look what I got out from the Deox-C fairy dust bath...

Just need to wait for flash rust now, then a quick lick of vactan and will be going back on the car.

By the way, wishbone bushes show how I grinded the top bit edge(maybe a mm or 2 of the inner sleeve flange) to fit a large socket to press on the outer sleeve, this way it all goes in easy and doesn't affect the bush in any way.

All went back ok, no problems at all. Had to get it ready for a 100 miles trip which also went well, clearly a big improvement, even if only one side done, drives a bit strange :)
I'll get to the other side, hopefully this coming weekend.
Had a good look at the calipers too, way past their use date, so will fit my refurbished set too. Passenger side, nuts look better than on driver side so fingers crossed, there won't be any dramas :)
Also, to answer my question re whether there should be any back and forth movement in the wishbone bushes, there shouldn't, all is nice and tight there :)
I'll post some pics later too.

Great post Katar, thnx!

I do keep saying it, we really must touch base as we're so close.

I've got a really great friend who Nakki has met and where my '40 and Rolls are; he's a "good old boy :) now aged 74 yrs old who is extremely generous with his kindness to me, also happens to have an early Walkinshaw XJR '40 and a two post lift in addition to a Mk7, an XK140 and and E type plus another fifteen assorted classics in various levels of presentation.

Sounds amazing carsie :)

Few more pics as promised.

Image

Wishbone ready to reinstall, only painted it in vactan.

New shocks

Image

And the old one

Image

Everything put back together, lots of copper grease everywhere too

Image

Image

and the spring for reference

Image

I'd say 20cm difference in compression. I've ordered a threaded rod and some high tensile dowel pins so will attempt spring replacement again soon :)

If only the factory had used that bit if copper grease to begin with, we would never have any of these issues now? Even if it added £20 to the build cost? I would have ticked that option on the brochure!

Good work Katar , you've brought back the front suspension from the dead , it certainly didn't look as though it had seen any love and attention for years , brave too , i didn't like the look of that spring just being held by the shock , especially after looking at the full length of it , still all credit to you it's done and no doubt when the other side is done it should drive better and last a good while too , thanks for taking the time to photograph it while you were up to your neck in it :)

Shock is there as a backup really, there is an axle stand underneath the lower wishbone there Derek, so its not going anywhere. I did however wondered what would happen if you slowly lowered the wishbone on that side :roll: Would it stay in the pan or shoot like a rocket from where its bend in the middle? Surely there must have been someone that attempted this madness, maybe didn't live to tell the tale... :lol:
Anyway got my M16 rod today so I'll have a go at it soonish.

Which ARB drop links did you opt for in the end? The genuine are expensive of course, and the aftermarket of dubious longevity?
Or PU?

I either got them from Berkshire or Moss Naki. Generally very happy with the item quality they both sell.

Bit of an update from yesterday. Generally it all came out easier than the driver side apart from two things. The lower ball joint does not want to come out, its proper stuck and no amount of hammering coupled with half hour torching the damn thing will get it out so I'm waiting for a heavy duty ball joint splitter this morning. Could have left it I suppose as it wasnt too bad as only two years old but I thought I replace it as I have a full set. The other thing is the lower droplink bolt. Its proper fused in the wishbone, in a same way as the driver side upper ball joint bolts were and we know how hard it was to get them out now :evil: I've managed to turn the head of it by half a cm each side but the bolt on the other side of the wishbone didn't move even a mm at which point I've decided to leave it as it doesn't really need to be removed and the thread is surprisingly still ok on it(afer a lot of wire brushing of course) so probably best not to touch it further :lol:
Speaking about upper ball joint bolts...

Image

They came out in one piece! 8-) Took 40 minutes to get them out but I didn't have to resort to cutting them, just had to cut through the ball joint nut as it got stuck and spinning with the ball joint half way through(same as the other side).

One thing I've noticed, spacers(between wishbone and ball joint) were put not as per Jaguar instructions diagram with 3 at the front and 1 at the back(all 4 at the front) so that means that either someone removed them in the past(which would explain why I managed to get them out in one piece) or it was used for some sort of a wheel alignment. How do I put them back now and what is their purpose?

This is the bolt that will NOT come out:

Image

This didn't work sadly:

Image

Any ideas whats this motor at the back which was in the way of the wishbone bolt? Took an hour to remove it as it holds on tiny 8mm x 1cm bolts with disintegrated heads :(

And the old wishbone bushes, completely shot as the inner and outer part of the bush was partially separated, allowing back and forth movement on the big bolt

Image

Cut them flush with the wishbone, then drill starting with 6 and finishing with 9, maybe 9.5 and then they easily hammer out

Image

Image

Image

Image

This process worked very well. For testing purposes I've tried to press them out first, using M14 bolt from a normal(not heavy duty) spring compressor and sockets and the bolt started to bend...

The new geniuine Jag bushes with the top spacer grinded a mm or two.

Image

Image

As I've explained, this way a socket can be put over it and it pushes on the outer sleeve directly, not on the rubber which makes its a mission impossible to press them in and distorts the inner rubber bush if you use the press...

Image

Pressed in:

Image

Image

One thing I've noticed, the diameter of the Jaguar bushes are slightly bigger than aftermarket ones so I've made sure to polish both surfaces and add more grease while pressing them in, otherwise it could have been much more difficult to press them in.

Re the bolts I've asked about in this topic, as far as I found out they are all 10.9 grade(or 8 for americans and maybe canadians? :D ) To confuse things, Jaguar used three different dimension types in their diagrams, starting from UNC through fractals to inches and of course they are all mixed up, even on the same JCP diagram!

Image

The ARB droplink bolts are 7/16 UNC/UNF, same for shock absorber bolt, they are only partially threaded though and the upper ball joint bolts, to confuse things even further, are M12 serrated bolts. ALL of these are of course quite expensive from Jaguar (eg ~£10 for the shock bolt) but are easily available and cheaper elsewhere.

Back to assembly then now... :)
