When I did mine, I sourced the rods from Grainger. They were not very expensive.

If the labour rate at a Jaguar dealer is one hour per spring that is a very good rate, and worth it. Even two hours a side is good, I'd say.
How do you think the pans are attached to the wishbones? Magic? Nope. With 4 3/8" Unf screws. And they carry the entire compressed load. And the threaded rod method uses the same screw holes, just that the screws are 12" long instead of 1". It is also a tried and tested method by many users here.

I agree with you Daim, but it is 6 actually, do not forget the two outermost nuts on the pan. But 4 is more than adequate to hold the spring while it is replaced.

Well, those screws hold other parts at the same time (like shock base etc.) But yeah, otherwise 6

I've removed springs on a variety for cars and tried a couple different methods on Jags.

FWIW....

There is always reason to be a little nervous.... as that's what helps keep you safe. However, I've used the 4-threaded-rods method numerous times and it's as good as it gets as far as I'm concerned.

Cheers

Yeah, for a mere $716.65 ! (£588.79 !)

Always good to remind everyone of the risks but the 4-threaded-rods method is tried and true....and within everyone's budget

I've used the rod method as well. However, as a precaution use grade 8 rods and nuts. Don't use some of the ungraded or grade 2 rod you can find at home improvement places. Stainless is also a poor choice, it's typically quite weak.

I stand corrected, but 2 hours is still a pretty good time to replace both springs starting and finishing with the road wheels on the car, and the car ready for the customer to drive away.

No, 2 hours just to put two springs into an axle. Not fitting wheels. Not removing the old springs. Not even undoing anything. My axLe was removed and was assembled. Just needed some springs put in.

With the rod method it took me less than 30 minutes to do both sides... So 320 EUR für a 30 Min job... That is an hourly rate I'd like to be able to charge... 640 EUR/h if I go by my numbers...
