How to assemble the differential case on Buick Rainier?

To build the Differential case, one should first lubricate the pinion and side gears with proper axle lubricant. Mount the Differential side gear thrust washers to the Differential side gears and insert the side gears and washers into Differential case back to their original positions if they are reused. Then, add the first pinion gear just in the middle of the Differential side gears, and the second one installment will also be located right opposite to the first one. Rotate the side gears until pinion gears come over into the opening of the Differential case, then install the thrust washers putting them in as pinion were rotated towards the opening. Install pinion gear shaft and fasten it using new pinion gear shaft lock pin with the hammer and brass drift. Before installing the ring gear with left-hand thread bolts, make sure that the mating surface of the ring gear and Differential case is clean. Hand-start all new ring gear bolts to ensure proper installation and tighten the bolts alternately and in grades to a torque of 83 nm (61ft. Lbs.). Lastly, install the Differential side bearings by inserting the j 8107-2 in the case backwards from the bearing installation and use the j 33790 Differential side bearing installer (J33790) and the j 8092 universal driver handle (J8092) to install the bearings.

The Differential is a part that plays a major role in guaranteeing high performance and durability of the Buick Rainier SUV that was manufactured between the years 2004 and 2007. Able to distribute the engine power in a very efficient manner to the drive wheels, the Rainier Differential guarantees steady movement when making turns and a steadfast grip in any terrain. With open and limited slip differentials available, the Buick Rainier responds diverse requirements of driving paving ways to fine tune the torque on the basis of tractions. This characteristic is highly essential for Rainier models which use front-wheel drive as well as the rear-wheel drive, and the 4WD types which has a central differential. A daily check of the Differential involves a few minutes of observation and it would also undergo maintenance, probably involving change of fluids or replacement of the U-joint since the lack or presence of fluids or a faulty U-joint poses a threat to the safety and performance of the Buick Rainier. The powertrain of the Rainier is very effective coupled with its differential and hence offers impressive acceleration with the V8 engine model taking 7.6seconds to accomplish the 0-60 mph. Also in safety facets, the Buick Rainier posses antilock brake age and GM's StabiliTrak system that guarantees safe driving. For that reason, the Differential is a reliability performer and safe vehicle that sets the rainier to be the mid-size luxury SUV in the market with comfortability and capability.
