Evening all,
Finally got around to removing and checking out the governer. To all that thought I was a little "off" thinking I had one with a removable cover you were right, I was wrong and request you consider my CRS is playing tricks on me. I thought for sure when I replaced the tranny a few years ago it had that type of governer. I did find that it had like a gunky stuff coming from the weights and the plunger/piston was a little sticky, weep hole clear on the plunger. Yes, I went ahead and changed the gear. The little that I got to check it it seemed to shift fine, best I can tell by looking at tach, when it shifts good it is usually so smooth you can't tell without the towd. Now after a short test run I found that the left front caliper hanging up, always trust your wife's sense of smell. They are already 80MM so I'll replace both, I bought the hoses a while back, guess it's a good time to change them too, I've read there is a possibility that the hose has an internal collapse and not letting the fluid release, I was able to pry the puck back. In the greater scheme of things pads and calipers are not that expensive. Also a good time to use the grease fittings and get some fresh grease in the hubs, 90% of the work will be already done. Just thought I would bring all you fellow GMCers that gave me suggestions and comments the update I promised.

Larry,
I drilled them a few years ago with the drill fixture and used the Set23's with the special grooved spacer from Jim K. I already had the special Chuck Aulgar tool before I put in the fittings so I put it on the studs and used the axle nut to push the shaft back from the seal, works quite neat uses the nut to push the shaft back toward center as you thread it outward, and give room for the old grease to escape, I've done this a few times already, I know it's not nessesary as much I do it, but it just makes me feel better about the front bearings. to quote forest gump "one less thing to worry about". But I most certainly appreciate your concern.
