The Stovebolt Site Forums The Shop Area Engine Shop Can't get lug studs out

Took the old studs out of the old flange on the 55.1. Can't seem to pound the new used ones out. Any tips? Thanks - Scott

Air hammer.

When I removed the studs from 68 C20 I used two mallets. I put a lug nut on the stud. Then put one mallet on the nut and stud and used the other to pound it out. Using two mallets leaves no fear. 8) You are also adding the additional weight of the second mallet, sledge or,,,

To remove the studs effectively the flange needs to be backed up with something. I made a fixture with 3- pieces of 3/4 inch pipe welded to a plate in a 3 lug pattern. With solid backing the studs will come right out. Without solid backing you risk bending the flange or breaking the flange.

If you are working with the front hubs, they are cast iron and break very easy. The rear axle flanges are very hard and have a lot of spring to them. With out a back up you are asking for trouble.

A press is another way to remove the studs, but you still need the back up.

A press like the one in this kit very easily and safely removes (and installs) wheel studs. No hammer is needed and no additional backing plate is needed.

I have one like tclederman and have used it for years on all kinds of stuff well worth the money ,the older We get the less We can depend on brute force , plus You brake anything on these trucks and it can be he** trying to find a replacement part.

TC et al:
After a few good raps without success, I went to Auto Zone and borrowed their ball joint press. It still took my 1/2" breaker bar and a good amount of pulling and tapping to get it out. It was swedged in there. I guess that was an overkill method they used early on and discontinued in later models. But...Thanks to all of you for your methods. I suspect there is more than one way to skin this cat, but the press worked.
