Very similar to what l made. I used a suitably sized replacement ball arrangement for tractor hitch at the pan, allows change of angle but guide rods in lower wishbone are still essential.
Remains a very scary task though when you realise just how much energy is stored in those springs.

A word of advise....not trying to sound preachy, mind you.
One of the times that I had a spring go wild on me was on a job I was really struggling with. Everything was fighting me. I was tired and frustrated....and getting careless.
I *should* have known to call it a day and get a fresh start in the morning.
When safety is involved you should be working with a clear head.

Bought some rod today... 1000 mm of M20, 4 nuts and 2 washers. Works nice though it is quite nerve wrecking. And I don't understand how Jaguar can fit such long springs in those areas and then still have a super soft suspension setup! ![Wink](https://www.jaguarforums.com/forum/images/smilies/wink.gif)
My springs had also fused together with the pan. That was a fight to get them separated!

Hey guys, thanks for the explanation. I'd like to attempt the spring replacement and get some sanity check from your side.
Is this all I need?
Why would I need another big rod in the middle of it all as shown on your pictures? Just to move the lower spring pan around?
Thank you.
Is this all I need?
- 4x M10 rods (how long do they need to be?)
- 4x M10 nuts (long)
- A specialized M10 hexagonal adapter which has the length of my rods so I can use the electric drill

@jal1234 thanks for your quick reply.
I want to go with the "4 rod method".
What size and style of rod is needed?
From https://parts.jaguarlandroverclassic.../brand/jaguar/
I see that the #12 "Flange head bolt" with parts no. JFB11011E, but I don't know size or type of the ripples on the bolt.

Would something like this be okay? 30 cm length rods with 3/8-24 UNF: https://www.ebay.co.uk/itm/271933379...8AAOSw~gRVqmgh

Then, if something gives way, the spring CANNOT escape.

Thank you. I also see threads https://www.jaguarforums.com/forum/x...pressor-82083/ and https://www.jaguarforums.com/forum/x...estion-230004/ have some info on the original jaguar spring compressor which just is a big rod in the middle. Saving here for future reference.

As far as safety is concerned, providing there is a safety system (a central rod or a strong tie for example) the four rod method is very easy and effective; after all once installed, there are only the six 3/8 fixings holding the spring on when throwing the car about on the road!

If you want to speed things up on the disassemble side of this job, cut the old springs in a few places with a cutting torch before removing the six pan bolts. springs fall out in pieces. Saves wear and tear on clamping tool. make sure you have new springs in stock.
Thank you.
