Was quoted 900-1000$ for labor plus cost of oil to regear front and rear Jeep JK '12 to 4.88. I later asked how much to weld on C-gussets, was quoted 2 hrs per side (I was fine with that). I had him replace ball joints while they were out. He later told me he had to drill out 2 wheel hub bearing bolts. He bought all 6 new bolts at $6 a piece, and on my invoice wrote "drilled out 2 bolts, tapped all 6 holes). I was charged for a total of 30 hours. This doesn't add up to me. If I subtract out $1000 for regear, that leaves $800 at $60/hr. Comes out to 13.33 hours minus 4 hours = 9.33 hours. I don't see why they need to retap the holes, he only broke 2 bolts. Even so, almost 10 hours on replacing those bolts is too long.
