Thank you for the information I have 2 10 bolt rears. On I I stalled on my 54 Chevy truck Ol'Beater. And I have a 86 Malibu rear gifted to me. It may be a possy, but it had water in it, and it's stuck. Both have ears on the bottom. The 86 Malibu, not as big But not plain like the one you show. My truck had a loose yoke. And a lot of play. I'm hoping after changing the seal ,and tightening the nut, the play will go away. But are the 2 rears compatible?
Not all 8.5s have the “ears”. A sure way to identify is the size of the pinion nut. An 8.2 has a 1 1/8” nut, and the 8.5 has a 1 1/4. Very easy to spot.
So I have a 79 chevy van with the 10 bolt 8 5. Everything if factory 350, automatic transmission. I am bogged down over 60 mph. Is it the rear end or the transmission causing the issue? Yes it shifts to third gear. I've heard of a rear gear upgrade. What's the best solution?
I have from what I've researched a rare 8.5. It has the bolt in axle flanges at the end. From what I researched it's pretty rare. Any idea how much it's worth?
Yes it is. I had a 7.5 that had 28 spline axles and i differential plate with brackets. And it held up to 500 horses with no problem. So you can run a 8.2. Remember back in the 70s 8.2 were capable of 400 horses easily.
@@Jared1970Monte I did alot of research. I found out about the “big 10” and the smaller 10 bolts in some of the mid sized gm cars. Mine has ears and it’s in a long bed c10. I’m pretty sure it’s a big 10
Jared1970Monte is there a way to measure it without removing it? I don’t have the time or money to source and wait on delivery of a specialty dial indicator
Got damn ... that was right on time, trimmed off the fat and right to the meat, thank you brother!!
100 videos and bunch of BS this guy gets right to the point thanks people should learn from him
Thanks for the clarification! Very straightforward and to the point.
Perfect video! Clear and to the point!
Great video no bs just straight to the point
Straight forward 👍🏾... Now I know my '84 Monte Carlo has an 8.5 differential...
Lol…I’ve googled and searched all over and this dude just made it cut in dry in about a minute
Glad it helped!
@@Jared1970Monte any easy way to know if it’s limited slip? I’ve heard ole lift the rear end truck doesn’t work on the 10 bolt style of limited slip.
@@chriswinkler8231 tag on the oil bolt is a possibility. Codes also
Thank you very much.
Don’t get no simpler than that right out the gate. I thank you
Thank you for the information

I have a 89' chevy suburban. 10 bolt.
I have from what I've researched a rare 8.5. It has the bolt in axle flanges at the end. From what I researched it's pretty rare. Any idea how much it's worth?
It is a pre 62 rear-end I ( believe) they were used alot then Chevy found a cheaper way and Chevy is always big on the cheapest way
Want to do 4wheel and put disk on my 10 bolt 8.5 for 69 JL8 set up for a 70 firebird !
👍 Thanks for pointing out !
No pun intended.
So I could just swap them over? Same u joints and such
I would double check that. I'm honestly not sure.
So is the 8.2 worth putting 3.73 posi into with 28 spline axles?
Yea i wouldn't put to much power to it. 8.5 is stronger
Yes it is. I had a 7.5 that had 28 spline axles and i differential plate with brackets. And it held up to 500 horses with no problem. So you can run a 8.2. Remember back in the 70s 8.2 were capable of 400 horses easily.
When I go online to buy a posi it says 7.5 and 8.5 how can I spot the difference between them?
7.5 8.2 and 8.5
Numbers will tell you.
8.5 has ears on the housing

What does 8.2 and 8.5 mean? Is it a measurement?
Yes. It's the ring gear size inside. 8.2" 8.5" 12 bolt is 8.875
8.2-8"1/4- 8.5/-8"1/2- 8.875-8"7/8 inside ring gear measurements
