Hi everyone
brand new on here. so go easy. im the proud new owner of a 1991 3.2 xj40 with twr sportpack and told it has self leveling rear susp and was wondering how easy to replace with standard? also would it jepordise the ride and handling? [8D]

 

it is actually recommended by jaguar to replace the self leveling suspension with standard shocks and springs,

the parts are no longer available for the self leveling, and it isnt actually very good,

standard shocks and springs can go straight in and the pipes for the self leveling can be capped

BB

 

the ride would be just as good or better
the job itself is pretty easy dealer charges about 4.0 hours
you most likely will be needing upper shock bushings also
i believe there are 2 upper bushings per shock
hope this helps
and good luck with the car

 

nice one my new friends, a big bill when it goes wrong then? thanks. only joking. thanks for the advice.

Acutually, the self leveling shocks are still available. I wouldn't recommend them, but they are easily obtainable.

The conversion kit comes with all associated bushings, etc. What you may want to look at is the springs. The Jaguar kit supplies new springs but most aftermarket units do not. If there is no sag in the rear, no need to do the springs. The question is what not do them since you are there. No need to do the job twice.

 

There is a reason Jaguar stopped making them. Jaguar is not prone to making unecessary improvements once they're fixed on something given all the other outdated things they did not.. it seems a good thing to make the change to the later years style of suspension....

 

The did have springs on the self leveling system. It's a coil over shock / hydralic setup. Spring kit for the good Boge shocks:

Yikes! I will check our sources and get right with the pricing. Thanks for the heads up. It's that kind of feed back that lets us know when we are upside down in the market place. Yes, those are the springs you need. The sagging springs may have worn your shocks out again. If they are Boge or KYB, they should have a lifetime warranty.

 

Hi,
I' reviving this thread (hopefully) because I want to replace the self-leveling suspension, too. I always thought that you have to replace the springs anyway, otherwise you get a bumpy ride. Now I've found this on http://www.autopartswarehouse.com/de...3-1613225.html I've read that some of you guys just replaced the shock absorbers, but don't you have a sagging rear end if the car's load? And if you run over bumps, does the rear end bounce? I've test-driven a Jag with a cheap conversion and it did this. And in another forum, someone explained that the SLS works on the principle that the rear springs alone are too weak to support the weight of car, so that the hydraulic system can control the car's height with the pressure in the shocks - sounds logical too me.

So my question is: Does the cheap conversion (shocks alone) really work, or is it just a solution that works good on even roads without bumps and potholes, and not if the car's loaded? And what might be trick with those KYB-shocks in the link above? Are they any different from the shocks you're using?
