Yukon Gear Master Overhaul Kit For 64-72 GM 8.2in Diff
Restoring a Chevelle, El Camino, Nova or early Camaro with the factory 8.2 in. ten-bolt? After fifty-plus years most of these rears have a hum at cruise, a weeping pinion seal or a clunk when you get on and off the gas. The Yukon Gear and Axle YK GM8.2 is the master overhaul kit for the 1964-72 Chevrolet 8.2: new Timken bearings and races plus every seal, shim and setup part needed to rebuild the center section correctly in one pass.
The Chevy 8.2 was GM's mid-size car rear before the corporate 8.5 took over in 1970 production. It is a C-clip axle: the shafts are held by clips on their inner ends inside the carrier, retained by the spider gear cross pin. The pinion runs on two tapered bearings preloaded by a crush sleeve, and the carrier sits on side bearings with shims that set both backlash and carrier preload. Original bearings in a car this old are usually pitted or loose, and once preload is gone the 8.2 ring gear walks out of its contact pattern and starts to whine.
The YK GM8.2 contains Timken carrier bearings and races, Timken pinion bearings and races, a pinion seal, a complete shim kit, ring gear bolts, a pinion nut, a crush sleeve, thread locker, marking compound with a brush and the cover gasket. It replaces everything that wears in the center section without forcing you into a ratio change.
Several ten-bolts look alike from a distance, so identify the axle before you buy. From the rear, the 8.2 housing has a smooth, rounded lower case that follows the cover outline, with no squared-off lugs at the bottom; the corporate 8.5 has two square chunks of casting there. Most factory 8.2 covers have an odd protrusion at the top. With the cover off, the cross pin lock bolt on an 8.2 takes a 1/2 in. wrench, while an 8.5 takes 5/16 in. The 8.2 ring gear bolts have 9/16 in. heads with left-hand 3/8-24 threads, and the pinion is 1.438 in. with 25 splines. If the axles bolt in through a retainer plate instead of using C-clips, you have the Buick, Olds and Pontiac 8.2, which needs the BOP 8.2 master overhaul kit instead.
This kit is listed for the 1964-72 GM 8.2 in. ten-bolt with C-clip axles, the Chevrolet design found in A-body Chevelles and El Caminos, X-body Novas and some early Camaros. GM moved many models to the corporate 8.5 in 1970 and 1971, so the year alone does not prove which axle a car has, and many old cars have had rears swapped. Use the identification points above, or send us your year, model and VIN and we will help check it. More differential and transmission kits are on our rebuild kits collection page.
A note on power: the 8.2 is only modestly stronger than the 7.5 ten-bolt and suits stock or mildly built cruisers. For engines heading toward 400 horsepower, plan on a stronger rear rather than a rebuilt 8.2.

No. Buick, Oldsmobile and Pontiac 8.2 rears use bolt-in axles and different internals. They take the YK GM8.2BOP kit. This YK GM8.2 is for the Chevrolet C-clip 8.2.
It could be either, since GM switched to the corporate 8.5 around 1970-71 and many rears have been swapped. Look for the square lugs at the bottom of the housing (8.5) and check the cross pin bolt size: 1/2 in. on an 8.2, 5/16 in. on an 8.5.
Timken carrier bearings and races, Timken pinion bearings and races, a pinion seal, a complete shim kit, ring gear bolts, a pinion nut, a crush sleeve, thread locker, marking compound with a brush and a cover gasket. Axle bearings and axle seals are not included.
Yes, if the teeth are clean and unchipped. Reuse the original pinion shim as a starting point and verify the pattern with the included marking compound before final assembly.
75W-90 gear oil. If the rear has a factory Positraction or aftermarket clutch posi, add limited-slip friction modifier.
