Buick 26014038 Cv Axle Shaft

These cars utilize two types of drive axles, namely the C-lock and the non C-lock type whereby the difference depends on the structure of the locking system. In the C-lock type the shafts are locked by C-shaped locks that fit into slots at the inner end of the shaft while in the non C-lock type they are locked by a backing bracket plate fixed on the axle housing. The bearings used in the case of the C-lock axle comprise an outer race, bearing rollers, and roller bearing cage with snaprings while the bearings used in the case of the non C-lock axle is a unit roller bearing which is pressed on the shaft up to the shoulder. Pre-service, it is necessary to determine the axle type and the axle identification number is located on the front side of the passenger side axle tube adjacent to the differential carrier, but not for models which used 8½ in. ring gear, which have the ID on a tag under one of the differential rear cover bolts. For the non C-lock type the process starts by removing the bearing retainer plate by pounding it using chisel and the axle shaft end play check that should not be more than 0.022 in. (5mm). The removal procedures involve the detachment of the wheel, tire, and brake drum as well as the separation of the brake line, the use of the slide hammer to pull out the axle shaft and bearing assembly. The bearing retainer is then machined in several places so that it can be removed; the new bearing is then fitted and all the parts put back. For the C-lock type: The procedure is initiated by loosening and thereafter unscrewing the lockbolt and rod upon the differential; by withdrawal of the differential cover and by the unscrewing of the pinion shaft lockscrew. The axle shaft is pushed towards the center of the vehicle in order to get rid of the C-lock, always being careful not to scrap the oil seal during the extraction process. During installation, a bearing puller is applied, the new bearing is lubricated, and correct positioning of the axle shaft and C-lock must be reached in reassembling the differential and then the axle is filled with lubricant. Last of all, brake drum and wheels are reinstated and a check is made for the leaks with the help of road test.

The first step is to raise the rear of the vehicle and securely support it.
