Get your lugs checked !!

BIGTIME · 10-27-2017, 08:08 PM

I have been reading on some of the ZL1 Facebook pages that the lugs on the car may be loose from the factory. I have a track day coming up so I decided to swing by Discount Tire on the way home since I got off early. Low and behold 15 of the 20 lugs on the car were loose !! Now its not like the wheels were going to fall off but only my front right wheels had fully tightened lugs. Im glad I swung by.

Just wanted to mention it to everyone. Have a great weekend

Good advice. I ended up with the clicking sound coming from the left front wheel around 1000 miles in. I took the wheel off, cleaned the mating surfaces, and reinstalled. A few miles more, the clicking returned. This time I went to the right front since it sounded like that's where it was coming from. Problem fixed once again. Then around the 4000 mile mark it seemed like I was getting the clicking again, but it was harder to hear. This time I grabbed my torque wrench and went to the rear wheels. They were both way under torqued. Almost loose even. So it's possible the fronts didn't really need to be taken off and cleaned, and just a simple retorque of the lug nuts may have solved the clicking.

What's the correct torque specs for the lugs?

140#

If you're going to be doing track days, my suggestion would be to buy your own torque wrench, and then you can easily ensure that the lugs are torqued to 140 lb/ft before each event.

the dealer is supposed to check lug torque during PDI. All of the studs stretch just a little so, recheck the lug torque numerous times during a track day. Wait until the car has cooled a bit before checking the torque.

This is a must. Those are going to loosen up as you spend time on the track and you're going to want to check them frequently. Do yourself a favor and put together a small plastic container with a "track kit" if you're going to track more than once.

Got them checked...basically no movement on any of them. All at 140#. I feel better!

I was a little surpised to see that he got movement on most , but some almost 3/4 turn!

will do. What was surprising was how loose they were before the car even saw a single lap.
