Rear axle fell out... (super crazy with pic)
Okay so my cars rear went bad i havent taken it apart yet but every1 thinks the pinion lost all of its teeth and was just bad. So i paid 200$ for a shop to rebuild the LSD rearend i had in the garage with all new bearings. I go to tow the car to my house so i can work on it over the 4d weekend and while towing it home about 1 mile down the road the wheel bearings (that i got pressed on new less than 300 miles ago) pressed off and the axle seperated from everything. The pic speaks for itself.. Im just glad it was being towed and it wasnt being driven and happen on the highway i probably would have died =/.

Yeah. Thats exactly what i was thinking. Like i was following the guy towing it and almost **** a brick when i saw the axle migrating out. This pic is like what it looked like the second we pulled over..

there are four bolts that secure the backing plate to the axle flange. this should NEVER happen and the backing plate should have been taken with the axle flange upon separation.. this means that whoever installed the new rear wheel bearings (axle bearings) did NOT install the bearing locking ring correctly or at all for that matter. the rear axle bearing (no the differential bearing) installation is at fault here. another reason why i do my own work. here is a pic of a completed drum axle unit with new bearing ready for install. note the backing plate flange and four retaining bolts sticking through the flange:

Nope it had the retaining collar on. I installed the axles on the wheel bearing change they pressed the bearings on. The 4 bolts in the backing plate are still in thats why it still attached lol.

You would be surprised at how old the technology is that goes into driveaxle designs on these things. In our particular case the mechanic made two mistakes...1. he did not pack the wheel bearings properly and 2. the endplay was set way to tight. The excess friction and heat did the rest. The dual wheels, drum and axle shaft all came out as an assembly upon failure. It was quite a site!

this is NOT an uncommon design, even the late 90's early 2000's Toyota Tacomas had a similar locking ring retainer design. it's probably still in use today.

The wheel bearings i supplied the lock rings i forgot to buy and the guy doing it said he would take care of it. I didnt get charged any extra $$ for retaining collars so he might have re used them.. im not too too worried about it cuz i have to replace the rear any ways.. Its just the principal of it like if i was driving in the car when that happened i would have a diff attitude towards it lol.

Bet the "took care of it" by just reusing the old collars. They'e cheap enough, so I would never risk that, but if he had to order them versus 'getting 'er done' he may have been tempted.
Hope the spline tips didn't get too beat up, grinding away at the inside of the axle housing.
