Repairing a rear axle

Everything except the truss on the underside of the axle housing. Reduction in ground clearance isn't good

Probably wouldn't notice it to much as it's still not lower than the diff head

When driving in deep mud or soft sand, it's a lot more mud/sand you'll pull in front af the axle, compared to no truss on the underside. Which is why I'd never install it that way.

Crickey. That Jimny doesn't look like it's ever been off road either!

I'm glad I have a spare axle but wouldn't want to be in that situation!

Is it just fatigue that causes it do you think?

guy I got it from reckoned it had been dinked in the wheel whilst parked 2years before it snapped so maybe weld had become fractured then tbh think its just a week point looks like most snap on the long side

Hello.

Thank you very much everyone for your interesting contributions.

Yes, the previous owner of the axle repairs wildly the half shaft and not replaces the side gear....






(I discarded both)

The lower axle trust is more effective because the underside of the axle housing is subjected to tensile stress, makes it more susceptible to cracking start it. Lamentably lower the ground clearance.

Placement both axles trust (upper and lower), with different lengths, prevents excessive shear stress in the axle housing, and jointly reduces the stress concentration by welding in the tube at the end of trusts.

I mainly use the jimny to climb rock mountains, sparsely in mud and sand
