See another thread about CL failure. This prompt me ask the question. How do you re-torque the CL wheels? My GTS has 2500 miles with stock CL wheels, with 3 track days. I never took the wheels off because I don't have the confident that I can put them back with every procedures done absolutely right.

Do I need to check and re-torque the wheels?

Can I torque the wheels without taking them off?

When I torque the wheels, do I have to lift the car and make the wheels off the ground? Can I do this lifting one wheel at a time?

Kind of worried to get on track again. Anyway, hope you guys understand my questions. Your advise will be appreciated.

Answers: Yes, Yes (but it is recommended to do an inspection of the CL hardware - see sticky above), Yes, Yes.

I highly recommend that you carefully read the 17+ step CL supplement in your owner's manual folder.

If you are not confident doing this yourself take your car to your dealer before your next track event and ask them to allow you to witness the full torquing procedure.

Get get the Precision Instruments Torque Wrench from ToolTopia.com for the higher torque CL's need, a nice jack and jack stands. See the sticky at the top of this forum and learn to torque your CL's. Also learn to disassemble the CL nuts, clean them and properly re-grease them with the proper Castrol Optimolly grease. DO THIS BEFORE YOU DRIVE AGAIN

If you frequently track the car, it is best to know how to do all this, and do it well. Obsess over the process, read the sticky on this thread, and search other threads. There are a lot of threads here with a lot of information.

Short answer: yes, after track events it would be wise to check the wheels, retorque, etc. And yes, it is advised that you only torque with the car elevated.

i just confirmed that two dealers got it WRONG on my cars.
the locking thread thingies are not engaged on some wheels.

Check out the thread link below. It will tell you everything you need to know about our CL wheels and then some...

I have seen this too (and too many times), by dealers and supposedly highly qualified independent Porsche workshops.

This is the reason in my answer to the inexperienced gent above in Post #2 that one MUST be fully familar with the CL procedure (i.e. read the supplement - several times) and ask to watch them work on your car so you can see it done (READ: to check their work!) and be comfortable doing it yourself afterwards.

that's scandalous! - care to share the names of the culprits so we can avoid them, or at least chastise them?

p.s
I wonder if any of the failures are as a result of this occurring?

1) Jack up wheel to be torqued.

2) Set torque wrench to 450 lbs.

3) Torque wheel to 450 lbs.

4) Put wheel back on ground

5) Make sure spline thingie engaged....put a 6" extension into the rectangular hole and make sure the center pops back out flush.
********************************
If you just want to check the torque...no need to remove wheel I would think, and thereby no need to put goo on the threads.

Thanks all.

I did read the thread and read the supplement before I post the questions. I just like to be confirmed and assure about the procedure.

So my understanding is that

(1) I can just torque the wheels without taking them off.
(2) I can jack up the wheel one by one and torque it. I don't have a lift. I only have one jack.

well, my fav dealer carlsen is one.
the other has "fixed" the issue.

P.J.S.

Don't you have to torque them and then back the nut off and retorque them?
Pre-loading them so to speak and all off the ground with the foot brake depressed and grease properly applied of course

mdrums

You missed a few steps....! And have the incorrect torque specs!

You 1st have to grease the conical surface on the CL nut....then torque it to 444ft lbs....then back off the torque...about a 1/2 turn of the CL nut and then re-torque to 444ft lbs and lock the splines.

LehmanZ06

So shoot me. I do it to just about 450 lbs----a smidge less......you mean you hit 444 lbs of torque exactly ??

I back off a little less than 1/4 of a turn, maybe 60 degrees....1/2 turn would be 180 degrees

I autocross and street drive.

(The original torque in our manuals was 379 lbs...how accurate did that turn out ?)

According to the update, it is 444 +\- 22, so i believe 450 is acceptable
