We have a 1998 Lumina Sedan, 3.1. Several of the front wheel studs
for the lug nuts are cross threaded/chewed up and pretty much useless.
(all I wanted to do was rotate the tires). If lugs are put on it just
chews the heck out of them. I tried to pound a stud out but there
doesn't appear to be enough room to pull it out. Is there a trick to
this or do I have to remove the whole hub to replace them? I actually
have to replace a couple on each side. Thanks.
You should probably take it to a shop and have it done as the drive axle nut
has to come off and it is torque at about 200 foot pounds. Anyway it has to
come off and the hub and bearing assy is bolted to the steering knuckle with
three bolts I believe. Take it to a good mechanic as you don't want to cross
Sorry it took so long to respond. The replacement studs are a
bit shorter that the OEM ones in that they do not have that smooth
'shank' at the end but the threaded portion is the same length. There
is a sweet spot at the very bottom of the hub assembly where you can
coax one in. So, I cut the ends off the bad ones; pounded them out;
then manuvered the new ones in.
