Overview
The G2 GM 218mm AAM Master Ring and Pinion Installation Kit, part number 35-2060, is a master set for a rear GM 218mm axle with AAM in the product name. G2 Axle and Gear classifies it as a master kit with bearings.
Installers replacing a 218mm GM gear set usually run short of the small wear items. This kit brings together shims, a pinion nut, a crush sleeve, seals, bearings and the sealers and compounds that go with them, so the rebuild does not stall while parts are sourced.
Key features
- Master kit with bearings
- Shim kit included
- Replacement pinion nut and crush sleeve
- Pinion seal with pinion and carrier bearings
- Ring gear bolts, silicone sealer, Loctite and gear marking compound
Before the gear rebuild
A ring and pinion rebuild goes more smoothly when the bench is clean and every part is laid out before the first bolt comes off. Inspect the carrier bearing bores, the pinion bearing cups and the pinion head for scoring or pitting, since a worn bore can shift preload even with fresh bearings. Check the axle tube seats and the cover surface as well, because they seal against the new gasket material.
Gear set-up is where pinion depth, preload and backlash are checked against each other, and the crush sleeve locks in those settings. Once the pinion nut is tightened to its crush point it cannot be backed off and reused, so plan on a new sleeve each time. Keep the gear marking compound handy for tooth contact checks, and expect the first miles on the new gears to bed them in.
- Clean the carrier and housing before assembly
- Inspect bearing bores for wear
- Lay out shims by thickness before the first measurement
- Replace the crush sleeve every time the pinion nut is tightened
