Alignment good, tires replaced and balanced.

Where to look at narrowing down? Suggestions I got were drive train, but there's three, how to tell their ok? Any front end things to look for?

 

When does it do it? When doesn't it?

 

Mostly after 80KM/hr on the highway, the winter tires are making it more pronounced. I also had them make sure the rims were true when they did the balance.

 

Have your shop look at both lower ball joints and your rack control arms. I recently had to replace both vertical control arms with ball joint and the steering rack for that same reason. Jaguar had a TSB on the ball joints. I also had to replace the bushings on the left lower control arm. Found it by lifting action on the rear wheel with the car off the ground.

See this TSB for Shimmy/vibration problems.

Thanks, on it....
I assume if I give the local jag shop my VIN, can they tell me these have been done? Do I have to push a little? Are they reluctant, especially a 17 year old car! lol

 

The dealer should be able to tell you if the TSB was done on your car. As for getting it repaired now, probably not as it was not a safety recall.

 

Sounds like a ball joint.

Lifespan?

 

Varies. Till they fail.

Things like driving on rough roads makes them wear.

 

OK, so, last night, driving home from a dinner, Nothing, I mean, maybe a little vibration, but driving on Goodyear Winter Ice treads I'm going to expect some. But nothing like the day I first posted, WTH? Now I'm really confused!! And sound a little flaky.

 

If the vibration is intermittent, it could just be flat spotted tyres which revert to round as they warm up. The S-Type seem particularly sensitive to it.

 

If it does it more at higher speeds, 65 mph plus, one or more wheels might be bent or damaged. Have a tire shop put your wheels with tires on the spinner and see if they spin nice and true, or wobble around. It happened to me with a couple of different cars and I replaced the bad wheels. Try this before you tear the car apart.

 

I did and they said theydid, I told them that I wanted to rule it out so they were extra careful to check, they said nope, look good, but pointed to the tire wear and said alignment, which is another story, I had it aligned, but the mechanic took it to another place and I don't trust that he gave them Brutal's (?) spec. I did call the alignment shop, they said they don't keep the spec, and that vibration and shimmy is not alignment, regardless, bring it in with your spec and we'll check it. Which I should do anyway before I ruin another set of tires.

 

Update, changed the sway bar bushing because of the horrible squeak, (see other post I made) and it has cleared up all the vibration. Oh man, I'm so happy, cost me $30 Cdn, instead of the $1000's the repair shop wanted to charge for a used drive shaft. I'm a happy boy. One by one I'm knocking them down.

 

Now that's a steal of a fix. Congrats....

 

I'm happy to hear your issue was resolved but I'm having hard time understanding why. Why would stabilizer bar bushing cause or not cause wheel vibration? Inquiring minds want to know. Thanks.

 

Those are the bushings on the bar itself, correct?

Did they look like they were binding?

 

I'm not too sure, it certainly wasn't my expectation that getting rid of the squeaky bed spring noise would remove the vibration at all!

 

Too me quite the opposite, the bushing (yes, sits "around" the bar) seemed a little crushed. And, as I mentioned in the original post, the bottom bolt didn't seem all that tight, was it tight when the bushing was put in originally and then as the material degraded it became loose? Might be something for me to check on the other-side, the one I avoided because the DCCV is my arch nemesis.
