If I remove the driveshaft.. can I just retorque the pinion nut.????
as insurance!!!?

Thank You... Chuck

 

It couldn't hurt. You can check it every 15k when you service the transmission.

 

Thank You, as I just serviced the transmission and final drive fluids 2,000 miles ago..

I will get back under the truck.. maybe this week.. and do a retorque.
but its under 32 degrees around here right now.

 

I got under the truck.
the 4 bolts holding the driveshaft to final was tough to remove. threadlocker worked well.

with parking brakes on. I could not move the pinion nut (On or Off) without rotating wheels. with 1/2 inch breaker bar. book said spec is 200 ft lb.. and I think it is...
added Red threadlocker to threads of pinion. and reinstalled driveshaft with threadlocker on there 4 bolts..

Thank You for your help and advice. Chuck

 

Greetings, went by the shop to check on my truck and all items have been approved to replace the rear end & drive shaft. Waiting on the parts to come in now. All new. The whole rear end. It was a hole in the bottom the size of a lg coffee cup. I saw the total cost as of now is $4087.00. Glade that I had bought a warranty when I got the truck. Who would think that I would have a problem with a truck with only 31000 miles. I was in perfect shape. Garage kept. Will let all know when I get it back..

 

that is good news.. and thank you for the update.

Question, do you or the mechanic know the cause of failure. pinion nut falling off????
pinion broke???

 

Chuck, They think the rod that holds everything together broke in half. Then all fell down into the bottom of the rear end.. Then all else history. It happen at about 30-35 mile per hour..

 

Just be glad it didn't happen while going any faster than that... that coulda killed you, and/or someone else if you were doing any faster....

 

Thank You again.
that is what happened to my 1963 Oldsmobile F85.. but I was going about 15 in a parking lot. way back in the day.

you had a part breakage. I feel a little better now.
spider gears ROD broke.. and all the spider gears went everywhere and no place to go.

Just curious, was that an aluminum block engine?
