You read stories and articles about installing new king pins (notta problem) if you have a big vice and torch and hammers and punches ? well I have a small benchvice and a few small hammers and punches, so I decided to take mine to a "real shop" and 2.5 hours and $225.00 later , wala new king pins. no busted hands ,high heart rate or colorful words(just had to work a few more OT hours)but worth it to me. You kinda gatta know your limits, and that was mine. lol
good luck , bowtie
