Q: How do you remove the rear axle assembly on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?
A: To remove the rear axle assembly, begin by loosening the rear wheel lug nuts and lifting the rear of the vehicle with jackstands placed under the frame. Remove the rear wheels and position a jack under the rear axle differential case. Disconnect the driveshaft and secure it out of the way.
Q: What is the type of rear axle assembly and differential used in Chevrolet Blazer,S10,GMC Jimmy and Sonoma?
A: The rear axle assembly is a hypoid, semi-floating type with a Differential that allows the outer rear tire to turn more quickly than the inner tire when the vehicle goes around a corner. The axle shafts are splined to the differential side gears, causing the inner tire to turn more slowly than the outer tire. The differential pinion gears roll around the slower side gear, driving the outer side gear and tire more quickly. The differential is housed within a casting with a pressed steel cover known as the "carrier," and the steel axle tubes are pressed into and welded to the carrier. On 4WD models, a fully independent front axle assembly is used, consisting of a differential and a pair of driveaxles with inner and outer constant velocity (CV) joints. An extension axleshaft is employed on the right side to make up the difference in distance between the differential and the right front wheel. An optional locking limited-slip rear axle is also available, which allows for normal operation until one wheel loses traction. This differential includes a pair of clutch "cones" that slow the rotation of the differential case when one wheel is on a firm surface and the other on a slippery one, equalizing the rotation speed of the axleshaft driving the wheel with traction. It is important to check for other possible causes before assuming the axle is the problem, as road noise, tire noise, and engine and transmission noise can be mistaken for axle issues. Overhauling the differential may require special tools and is not typically cost-effective for a do-it-yourselfer.
Q: How do you remove the driveaxle on 4WD Chevrolet Blazer,S10,GMC Jimmy and Sonoma?
A: To take out the axle shaft, start off by loosening the wheel lug nuts and raising the motorcar with jackstands. Remove the wheel and use a prybar or big screwdriver to hold the axle shaft while loosening the axle shaft hub nut using a big breaker bar. Get rid of the nut and washer. Then, keep hold of the axle shaft in position and clear away the axle shaft flange bolts ensuring you label CV joint inner to flange interconnectivity before eliminating these bolts. On 1999 on models, there are no axleshafts which are flanged to differential housing anymore but they have snap rings holding them at inside closed end of spline ends at trilobate joints. To free up an axleshaft, thump against it somewhere on its tripod container with wooden hammer until it snaps out of place from its groove. Take out steering knuckle then remove also halfshaft assembly. To reinstall proceed vice versa however when doing that ensure that you properly torque rear cv joint bolt and tighten front left outer cv joint as well as right outer cv joint hub nuts.
Q: How do you remove the rear axle on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?
A: To start the process of removing the rear Differential, lift the rear of the vehicle and support it securely using jackstands. Take off the wheel as well as brake drum. If there is a locking differential on that vehicle, remove both rear wheels and brake drums. Remove the cover of your differential to let the oil drain into a pan. For traditional differentials, take out pinion shaft by extracting lock bolt. Using an assistant push in on an outer flanged end of an axle shaft while removing any c-lock from groove inside opposite end of a shaft. Turn over such a differential so that you can gain access and support its pinion shaft in order to avoid it falling down into case when working on locking type differentials. Partially withdraw your pinion shaft by taking out its lock bolt and rotating this type of differential until a shaft touches case allowing enough space for clearing out to c-locks. Use screwdriver for twisting c-lock until open endpoints are aligned then insert axleshaft back in then remove c-lock which is compressed at this time, repeat procedure with another axleshaft also with C-Lock no longer in place carefully pullout axleshaft because it may damage oil seal if not taken with great care some models may have a thrust washer in diff make sure it doesn't fall out when removing axle shaft next, take care inserting this part into housing so that it seats properly inside differential always used on typical differentials putting lock on flange must be used to achieve this result put C-Lock back into groove on axle shaft slide backwards using correct positioning after installing C-locks after withdrawing axleshafts slowly until C-Lock clears thrust block now that c-locks are installed push pinion shat through position where hole lines up with lock bold hole then install lock bolt at last install cover and fill diff with specified lubricants reinstalling brake drums and wheels followed by lowering car.
