if2dc Posted October 14, 2017 Share Posted October 14, 2017 While replacing the front brakes and rotors on my 12 LGT today I got a nasty surprise courtesy of my local dealership. I made the mistake of letting them rotate my tires and they over torqued and ruined the threads on multiple front hub bolts. Can hub bolts be replaced individually or am I looking at a full hub replacement? Sent from my XT1585 using Tapatalk Link to comment Share on other sites More sharing options...

dgoodhue Posted October 14, 2017 Share Posted October 14, 2017 See if this is what you need some dealer No need to disconnect the battery, remove the ABS sensor, or dust shield, you just need to remove the brake caliper and I remove the brake rotor., beside obviously jacking the car up and removing the wheel. I had to replace all 20 studs on my GT. They make a tool for install and reinstalled studs. For one stud, in the past I have pounded them out with a sledge hammer and torque them on with the wheel.

YeuEmMaiMai Posted October 14, 2017 Share Posted October 14, 2017 the front bolts are easy to change buy replacement studs plus 6 flat washers 1. loosen lugs 2. jack up car 3. remove wheel 4. a. remove caliper and bracket as an assembly and hang from spring using bungee cord b. remove front rotor b. rotate hub so stud is at the bottom position of hub 5. use hammer to hit stud until it comes out 6. put a little oil on new stud's ribs 7. insert stud into hub 8. place washers over stud 9. use lug nut to draw stud back in until it is flush with hub repeat steps 4-9 for any other studs messed up on wheel 10. replace rotor 11. replace caliper assembly 12. replace wheel 13. put lugs back on and tighten just enough to keep wheel from moving if you tug on it 14. lower car 15. torque your nuts to spec repeat for other wheels if it is a rear wheel 4 a. remove caliper and bracket as an assembly and hang from spring using bungee cord b. remove rear rotor b. rotate hub so stud is in a free area of the rear parking brake. To make it easier, you can unclip one spring and move the shoe if needed.. make sure that you re clip the spring when you are done with that wheel.

Sarang Posted October 14, 2017 Share Posted October 14, 2017 That sucks. I have had a similar experience: I had to replace two each on my rear wheels. I ordered this: https://smile.amazon.com/gp/product/B00GHQRK8G/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Which is a pack of 10. It's honestly pretty easy, just remember to not put your parking brake on so that you can rotate the hub tot he spot where there's room to replace 'em. Pounding the old out and drawing the new in is very very simple. Don't forget to check the lug nuts on those wheels the next few times you drive it afterwards.

These steps aren't even correct for a 5th Gen. Link to comment Share on other sites More sharing options...
cww516 Posted October 15, 2017 Share Posted October 15, 2017 I just did all 20 on the Baja not too long ago, after I had one snap while I was taking the lug nut off. I got the studs from Rock Auto for something like $22 plus shipping, and I grabbed a stud installer from them as well (there'll be a "hey, do you want this, too?" link in your cart when you add the studs). You could skip the installer and go with a stack of washers and a jam nut, but $18 for the correct tool for the job wasn't bad at all. Also, for removing the existing studs, go to your auto parts store of choice and rent a GM tie rod end removal tool, which looks kinda like a C-clamp with a clearance cutout. The fingers hook over the back face of the hub, and you can push studs out really easily with an impact wrench. Not sure if it's absolutely necessary, but your wheel bearings may thank you.

if2dc Posted October 15, 2017 Author Share Posted October 15, 2017 Thanks for all the info guys. Since I just did my own rotors and brakes, most of the steps are fresh in my mind. And it sounds like the remaining steps for removing the old stud and inserting a new one are straight forward.
