Hi guys, I had new tires installed on my car today. The installer said that when he was tightening the lug nuts after the install the front wheels were rocking back and forth. He grabbed the driver's side front wheel (after the car was back on the ground) and rocked it back and forth to show me. He said he's not familiar with the S-Type but that's usually a sign of bad control arms or ball joints.

My car has the 18" Triton wheels on it. It drives really tight, there is no clanking or thumping when I drive or when I turn. I can take video to show you what he did if it helps.

I'd appreciate your thoughts, And of course, if I should stop driving the car. The last thing I want is for a control arm to brake and destroy the car!

Upper a arm comes to mind. The entire spindle is held by a triangle of ball joints

 

+1 on upper control arms and lower ball joints. The outer tie rod ends are also subject to wear and can cause erratic steering.

 

I agree but if in doubt take it for a second opinion.
It's a tribute to the Jaguar front suspension design that parts can be so worn out and yet the car still drives fine.

Thanks guys, I'll have it checked out.

 

What did the tire shop think? Seems they should have the equipment to investigate, such as a lift and a nice pneumatic wrench to make that spiffy bap-bap-bap noise.

Are the rims new or have you had them a while? If new, I wonder if they don't fit properly.

 

I just replaced one of my front wheel bearing and hub assemblies for this exact same reason. Les Scwab wanted about $500 to do just the one side and I ordered mine from Rock Auto for $70 and did the work myself. Took me about an hour and it was easy
They are self contained (hub and bearing assembly) and include the speed sensor

 

I think I need to replace one of my hubs as well because I can hear a noise but I really can’t feel it in the way the car drives or if I get out and try to crank on the wheel with a crowbar doesn’t seem like it’s loose but I hear that noise in the front right.

to the OP are you saying the top of the tire could move axially in and out when the technician told you it was rocking back-and-forth? How far would it move? Seems weird that you would have that kind of movement and not be able to feel it when you drive.

See post #20 for how I isolated the source of noise. I'd hear the rumbling noise on straight roads and gentle turns. In sharper turns at speed, this put a side load on the bearings and quieted the noise.

 

Jack the car up, be sure to either use jack stands or make sure you dont put yourself in a position to get pinned under the wheel or body . Grab the wheel with both hands at 12:00 and 6:00 while the tire is still on the car and try to rock the wheel. if there is any play whatsover it is most like the wheel bearing assembly

 

Hi
Ive seen this first hand with cheap front banana arms
the big bush on the cheap ones are crap, and the front wheel can be made to move over a inch, by just pressing the brake at rolling speed
they make the car handle like a proper boat
cheers
