Transtar's Differential Overhaul Kits include: 

PinionBearings.pngFront and Rear Pinion Bearings & Carrier Bearings

Pinion bearings are designed to reduce friction in the direction of desirable movement, increasing efficiency. In drive differentials, pinion bearings help the smallest gears in the differential work smoothly. Differentials are made up of a series of gears and cogs, and it is the smallest gears that allow one wheel to safely rotate faster than the other.
 

Pinion Nut

Pinion nuts secure the driveshaft yoke to the pinion gear. You should replace original worn or damaged pinion nuts each time a gear set is changed.


Pinion Seal

Each pinion shaft will have a pinion seal, which is used to ensure that fluid does not leak out of the differential past the shaft. Depending on the setup, you may have a rear shaft, or a front and rear pinion shaft.


Crush Sleeve

A crush sleeve is designed to prevent your pinion bearings from being preloaded too tightly and prevent the pinion nut from loosening up.


Gear Marking Compound with Application Brush

To check the gear tooth pattern, paint several ring gear teeth with gear marking compound. Rotate the ring gear so that the painted teeth contact the pinion gear. Move it in both directions enough to get a clearly defined pattern. Examine the pattern on the ring gear and make the necessary corrections.

*Axle Bearings and Axle seals are sold separately specific to application
