I have a 99 Tahoe, few weeks ago I was driving from work and my front driver side wheel came off rite when I was getting off the freeway, idk what happen but I had to replace all the studs and lugs on the wheel, it now wobbles and I always check to make sure my lugs are tight, some of them come lose sometimes & I have no ideal whats causing the problem. If I can get some help it would be very appreciated....It worries me a lot as I do use it a lot.

 

If it's coming loose I would recommend replacing the hub and rotor with OE GM parts. It sounds like you have bent stuff and whoever replaced the studs didn't do their job correctly.

And how tight are you calling tight? If you're standing on a 1 foot wrench you probably aren't getting it tight enough. Specs call for 140ft/lbs of torque *per nut*.

 

Maybe somebody doesn't like you, and they are loosening your lugnuts. Go buy 24 locking or external splined lugnuts, and a torque wrench.
