Hi,
I have a jaguar that experiences vibration between 60 and 80 MPH. I checked all the linkages and I have new tires and everything is balanced (double checked this). I noticed that my sway bar moves back and forth a bit (slides through the bushings) I don't know if this is a problem or not.

I also recently found that my right axle has a bit of play in it (on the connection between the half axle and the inner axle) So I replaced this.

The vibration doesn't seem to have gotten much better.

I also found that there is a bushing that holds the transfer box (keeps the engine from rocking back and forth it seems. This bushing is ripped in my car and I would like to replace it but i don't know what it is called or how to find it. I added pictures to its location

Could this be the source of vibrations. What else could it be? Opposite Side of Bushing
Outside of Bushing
Bushing Photo (lots of play)

 

I believe the part you are looking for is the Roll Restrictor. I have attached a blow up from SNG Barratt a forum sponsor. You can go to their website and download for free an electronic version of the X-type parts catalog.

Should my vibration go away if i replace this. I'm going to give it a try and replace it.

Does anyone have experience in replacing one of these?
