Removal


1 Drain oil from rear axle.




2 Unscrew caliper at respective end and hang up with a hook. Not required for rear axles with starting torque compensation.



On rear axle with starting torque compensation, if required, unscrew brake hose on holder and close brake line as well as brake hose against penetration of dirt.





3 Loosen hex bolt M 12 of 1st version or hex bolt M 8 of 2nd version with spacing sleeve and clamping disc for attaching rear axle shaft to rear axle shaft flange and remove.




4 Force rear axle shaft out of rear axle shaft flange by means of assembly tool.


Attention!
When removing assembly tool, be sure to hold rear axle shaft in place. Do not permit rear axle shaft to drop, since this will damage the synchromesh joint and result in leaks. If on models 114 and 115 the rear axle shaft cannot be removed in spite of being completely telescoped, loosen upper shock absorber suspension and lower semitrailing arm against deflection stop.

On models 107, 116, 123 and 126 loosen rear axle center piece from rear axle carrier and lower until studs are out of rear axle carrier (concerns mainly vehicles with starting torque compensation). Swivel rear axle center piece to pertinent side until rear axle shaft can be removed.





5 Support rear axle housing with pitlift or vehicle jack and respective top.




6 On 1st version of rubber bearing, unscrew hex. socket neeked-down bolt for rubber bearing on rear axle end cover. (Model ll4 and 115) On 2nd version, unscrew hex. bolts from rubber bearing.

7 Clean rear axle housing. Unscrew hex. bolts for attaching cover to rear axle housing and remove cover.




8 Pull off locking ring (26) between inner synchromesh joint and side gear by means of pliers (1) or a hook and remove from housing.

9 Pull rear axle shaft out of side gear and remove together with spacing ring.
