To follow up. GMpartsgiant took 1 wk to ship parts. Then 1 wk for UPS to get parts to me. 1st hiccop, I had remove what I think is the oil pressure sensor & oil filter to get to case extension bolts, so had to make a trip to store for oil & filter-$25, but thats ok--time for change anyway. 2nd speed bump, TRANSAXLE BRACE, diagram ref # (9)! Those 2 bolts are not easy to get to. 3rd road block, VEHICLE SPEED SENSOR RELUCTOR WHEEL, diagram ref # (713)!!!! I could use some adivce here.
This is 1st time I've held a diff in my hand, I failed to research this part, I assumed it would slip onto diff (700). Once I had old diff off, I learned how wrong I was. GM service manual says, do NOT remove wheel (713) unless it is damaged. & install procedure is to hammer it onto diff.
I have a generic puller, I could try to get wheel (713) off old diff, but I would rather keep old part in good condition unless I have reason not to. & I REALLY do NOT want to put on old wheel (713) on new diff, then have it not work properly and have to take it off again.
So, can wheel be removed without damaging it & reused? Or am I stuck w/o my dd until I can get new wheel (713) delivered?
