I purchased my GMC recently and don't know its history so I had already
determined to replace all wheel bearings & seals. Replacing the studs
sounds like a little extra work. Removing the old, rusty bolts which
hold the brake drum and hub together has turned out to be more than a
little extra work. The bolts are recessed inside the brake drum and
require an extension making it difficult to control a cheater bar.
Further, they are too close to the hub to allow a thick walled impact
socket to fit (minor problem). The studs themselves have not been a
problem. This is a manageable, but a significant task. I will probably
clean threads up with a tap and die and remove all oil, liquid wrench,
etc. with solvent prior to reassembly.
I am working on the back wheels and I see no danger to the bearings and
seals in just replacing the studs. If I were not replacing the bearings
and seals, however, I would say that installing longer lug bolts is not
worth the significant effort. Jerry.
