It took almost 4 months, but she finally moved under her own power again today. The axle is in, the u bolts are torqued, and the brakes work! Now time for new front wheel studs and license and insurance. Has anyone drilled out the front hubs for 9/16 studs? I found a few threads where people talk about it but I never found one where someone actually did it. I keep finding conflicting advice on whether or not I can drill or if I need to use a reamer.
