hey guys i have a 2012 xjl just changed brakes and rotors in the front with texture rotors and oem pads. Riding on oem 245/45/19 Pzerro all season i am having shaking in the steering wheel at speeds over 25 mph the shaking increases as speed increases but noticed that when i turn the wheel to the right the shaking stops but still shakes when turning left braking is fine and smooth and shaking slows down as speed drops also hearing a slight rattle in the front end when i am rolling away at 0-15 mph

 

Were the discs checked before installation? One may have been dropped and is out of round. I would suspect the front right.

The brake job could be just a coincidence. Without experiencing it, it's hard to say.

First thing to do is to take it back with the complaint.

 

If it's shaking on driving but not vibrating on braking then it's more likely to be a wheel balancing issue (or bent wheel). Maybe they knocked off balancing weights. Definitely take it back

 

So not even 2 hrs after my post i had to get it towed the shaking slowed down but felt like i was losing control of the steering and loud knocks called the specialist he said may be wheel bearing will update tommorow when he gives me a call with the finding thanks for all of you alls help

 

Balance weights or a loose wheel,(don’t ask me how I know!)

 

That sounds like a loose wheel to me. That would have been the noise you heard at low speeds. Someone didn't tighten the lug nuts I'd bet. If that's it, better have then inspect the threads or just have them replace all the studs.

That's a job that the new kid gets usually. The mechanic probably told him to put the wheels on and he put them on finger tight and forgot to hit it with a torque wrench or even an impact wrench.

I knew a shop that had an oil pit. One kid on top the other on bottom. The top kid thought the drain plug was in, the bottom put it in after all the new oil drained out. The owner got about four miles down the road. Not a one of them recognized the sound of the rods knocking until it was too late.

 

+1 on poorly trained wheel/tire techs. Also. wheel torque specs in their computer may be wrong. See your Owners Handbook. I'm pretty sure it's 92 ft. lbs. Excessive and uneven torque can cause wheel shimmy.

Noted that work was done in Washington, D.C. area. Odds are that the technician used the wrong size socket with an impact wrench and buggered the corners of the lug nuts, thereby preventing one or more from being tightened to the 92 ft. lb. torque spec. I insist that wheel techs use only the OEM metric (European) socket and R&R the wheel with hand tools; otherwise. they'll use an Impact wrench with an SAE (American) socket that's just a wee bit too big, which will make it very difficult, if not impossible, to remove the lug nuts.

Jaguar uses a 2-piece lug nut, with a chrome exterior shell, that an impact wrench with the wrong size socket will damage and cause to spin around the interior nut. Make sure to have that brake shop remove ALL the lug nuts and inspect them for damage. If they're buggered, they caused it and should buy new OEM lug nuts.

 

So just got word back... looks like lug nuts screwed me here he said he car was missing lugnuts which caused the problem. From that the front left well broke a stud off so i have to replace the whole bearing since front studs aren’t sold separately also damages the wheel will require a new wheel total repair without new wheel will run me $900 bucks thanks alot


as for the training of the shop it is called master auto jaguar in Kensington md there are a certified shop with a expert level techs the head tech has been recognized by Jaguar Motors and even flown out to the main manufacture for expertise training so i don’t discredit their work.

i believe this may be due to not using OEM lug nuts as i purchased the vehicle with aftermarket 22in rims so the lug nuts were changed... waiting to hear more back but that’s the update

 

If this had happened to me I would lay it all back on the repair shop to repair at no charge to you. It was obviously a mistake on their part. Maybe they used an air gun to tighten the lugs and didn't check with a torque wrench to make sure the wheels were properly tightened or they stripped the nut by over tightening. IMO

 

They didn't put the lug nuts on more than finger tight. That's why they were missing. They're laying on the side of the road somewhere. Accidents can happen in the best shops with the best intentions, somebody handed it off to the new guy and somebody called him off before he finished and he forgot to tighten your wheels when he came back. I've seen it happen before. The shop should fess up and repair the damage and you can go from there. I've been there and watched these things happen, people will never be perfect the test is in if you own up to it.

I took my Firebird in once to get the tires rotated. A month later the brakes started squealing as I drove across Alabama. When I got here I told my Mother to grab her keys and bought some pads downtown. The next day, Thanksgiving, I'm under the car doing a brake job while Mom is cooking Turkey. I found a lugnut cross threaded on the left and one on the right. I tightened the other four and threw away the studs that I broke off.

When I got back to Georgia, I went back to the shop and they had hired a new counterman, I explained what I found and asked him what he was going to do about it. Without asking for a receipt or anything he blurted out, we're gonna fix it. He took the keys pulled it right in and replaced both studs immediately. He had it fixed and me driving home in 10 minutes. He didn't even try to charge me for it. His shop did all my work after that for 10 years.

 

so just got my cat back after the repairs...after careful thinking came up with the conclusion that the lug nuts used were to small. The problem was my car was fitted with 22in rims and when i swapped back to oem because of winter season the same lugs nut were placed back on the oem wheel which has a larger opening for the stud then my 22s. From this the wheel was loose and the lugnuts were to small as there were tuner lugnuts to accommodation the fitting of the 22 in rims.


What can i say mistakes happen every day and a 900$ repair for a new wheel bearing pplus lug nutts all the way around and labor was well worth it as being without my cat was driving me crazy!!!!!

 

The facts of your Post #11 aren't clear. Who put the 22's on, you or a previous owner? When was the brake job done, before or after the OEM wheels were put back on for the winter?

If you did the wheel swap yourself, then it was your fault that you used the wrong lugnuts on the OEM wheels. But if you had a wheel and tire shop do it, then they should have known to use the OEM lugnuts with the OEM wheels, and not the tuner lugnuts, and should be responsible for the cost of repairs.

 

 

It should have been obvious to a trained wheel and tire tech that the tuner lug nuts were incompatible with the OEM wheels because they were the wrong size or had different types of seats. But to get them to accept responsibility is probably an uphill battle.

Just curious - did you buy the all season tires from the same shop that sold you the 22's? Did an authorized Jaguar dealer sell you the 22's?

For more information about lug nuts, including the different types of seats, see my Posts ##13 snd 16 in this thread: www.jaguarforums.com/forum/xj-x351-53/continental-dws-06-a-153244/

Fortunately, you stopped before a wheel fell off and caused greater damage and injury. It could have been a lot worse. Glad you're back in the cat and the work was done to your satisfaction.
