Diff's rebuilt....

[thrashingcows]

Just got back from picking up the crewcab. I had taken it to a local diff only guy I have dealt with on a few things over the years. I went to him for a re-gear from 4.10 to 3.54 and rebuild as necessary.

He told me both diffs were in good shape, someone relatively competent had been in there at some point. Power loc only needed new clutches, and the front diff didn't even need new bearings.

Re-geared to 3.54's, I had an OEM ring and pinion I had picked up super cheap. I went to a old fellows house to pick up a compressor and when he saw my crewcab we got to talking. Turned out he had recently sold his 92 reg cab dually and had some leftover pieces. I got a mint, but terribly bent one ton tailgate, Dana 70 3.54 ring and pinion, repair manual and some other stuff for $125!

Anyway he only had to replace the front gear set, with a mint OEM set. And he couldn't say enough about how clean and easy my stuff was to work on...such a change to what he usually has to deal with.

All in all a very fine experience! I would highly recommend him to anyone in the area!

If anyone is interested this is his business....

Just got back from a drive with a GPS unit to confirm my current speedo reading, to my actual speed, now that the gearing has been changed.

I first removed the ratio adapter that was in there. It was a 1.04 unit, which was a 4% increase in signal speed for the 4.10's. I then re-installed the VSS straight off the transfer case.

I had read that after you do this you go for a drive, then drive 50mph (80kph) and check your speed. Mine was 67kph. Then divide your speedo reading into the 80kph and it gives me 1.194. So I need a ratio adapter with approx a 1.2 over drive ratio, or 20% increase in signal speed for my speedo to be accurate.

I'm going to the wreckers in a bit to see if I can find anything.
