Hello all, I am new to this forum and have a question. I have a 92 F-150 4x4 that has a leaky rear main seal. I have replaced these on cars before but never a 4x4. Can anyone explain what is involved in this. I got a quote for $1600 and I have been out of work for a year and certainly can't afford this and would like to do it myself. Thanks in advance, Billyzack in Phoenix
