The Stovebolt Site Forums The Shop Area Driveline replacing wheel studs

I am trying to replace some broken lugs on my 49 1/2 ton. I have beat them with a hammer, applied heat and still cannot get them to budge. Does anyone out there have a solution to this problem??? Also what is the size of these lug bolts. Thanks for any help and advice.

I used a hydraulic press to remove and replace them on my truck. They are a very tight fit. The thread size should be 7/16" UNF.

A hydraulic press from front wheel lugs. This tool works well for removing rear wheel lugs with the axle in place. The tool goes on sale often (sometimes at 50% off).

It looks like wages are going up outside the US? A few years ago, this set cost about half what it sells for now.

It looks like the length of ribs and length of threads are different on front and rear, and there were differences between 1950 and earlier and post-1950.

I had the same issue - I tried to pound out the front with no luck. Later I learned that a brake shop has to "swag" the studs using a press - not something to do at home. (I felt very ignorant once again for the time spent pounding and cursing!)

I do appreciate all the responses. What kind of ball park price are we looling at for the hydrolic tool to remove these and have you been able to use this tool on any other projects???

I had a couple real stubborn and cut them off then drilled them out.

the first tool Tim linked is the only type of thing that you might use for other jobs, but the studs can be overcome with patience

originals are usually swedged so they won't walk if the lug nuts come loose, this may be visible as "chisel marks" on the heads, using a big cold chisel against the side of the head where the marks are might loosen the stud - if not, try drilling from the backside with a bit at least 1/2 the diameter of the threaded end - center punch it well so it stays centered - drill deep enough to be past the knurling - then turn it over and with a short piece of heavy wall pipe around the stud head, try the BFH again

Take and soak them with a spray can of PB Blaster as they might have some corrsion issues. I used a Cross Peen Hammer to get two of mine out then sprayed them with PB. when I pulled them in with the old lug nuts and some washers and a impact wrench.

Front axle removal. Not hard at all. Disassembling the parts on the axel might be a little more difficult.

What front stud are you referring to?
