Rearend and Brake Upgrade...

[99 GMC Yukon]

I have slack in my rear differential which is supposivly common? It makes a awful noise, clunk. Im wanting rear disc in the rear and maybe something a bit tougher in the front. I was just kind of wondering what everyone is running if they have done any upgrades pertaining to this?

I too want to upgrade axles. Look into the light 3/4 ton rear axle. Its a six lug semi floater 14 bolt. Still drum brakes though.

IMO disc brake upgrade in the rear isnt' really necessary.

find all posts by JP422. Joe has both front and rear disc upgrades on his 99. That should give you a great start for the brakes portion of your project. and wwelcome to the forum.
