Rear Axle Bearing failure
 
A month ago I was hot-rodding my cart in some garvel and I heard a terrible sound from the rear during a power-slide. I drove around the block and continued to hear things popping and cracking. I put the cart away and ordered up a fresh hub/drum figuring I had stripped another one. Life happens and the cart sat for a month before I got up to the campground and was ready to work on it. I got it in the air, removed the driver's rear wheel, removed the axle castle nut, and pulled the drum off. As the drum came off, the axle shaft came right along with it:

That's not supposed to happen. Bearings started falling out along with other chunks of metal and rubber:

Inspection of the axle showed the bearing inner race still on the shaft:

Inspection of the axle tube showed a mess left behind. These were the remnants of the sealed bearing:

The outer race of the destroyed bearing was left inside the axle tube and could not be removed easily:

Rented (free) an axle puller kit from Advanced Auto and rigged it to remove the outer race:

Next problem was the axle seal, which was also crushed and had to be removed the same way:

Current status: the cart is still on the jack stands. I found a bearing locally, and it may not be correct. When I place the bearing on the axle shaft it spins on the shaft. It should be a press-fit, but it slides on and off by hand. There is no play on the shaft, but I'm not convinced it should spin. Other supervisors (friends holding beers) suggest that when the cart is on it's own wheels the load will keep the bearing from turning on the shaft. This is easily proved without installing it. Also, I could not find an axle seal at all, so I am waiting for parts from Scottyb's Carts Unlimited, a BGW site sponsor.

Everyone I have ever installed it had to be pressed on. Spining on the axle isn't normal!:thumbup::help:

That sucks G.

Any ideas on what might have caused it to fail?

2 New Bearings and seals are on their way :thumbup:
Here's my thoughts ... 1997 cart. Sealed bearings designed to withstand 5 yrs of golf. Subject them to 10 years of additional abuse with a large man and fast motor. :-P Metal can only take so much :lhmo: The results are posted above 8)

The two ruts my rear tires made in my gravel driveway lasted all month. I smoothed them out with a rake today because I was sick of looking at what I had done. This one is my own fault. That PQ motor has a truckload of torque!

Scottyb says I will have parts by Thursday. Thanx, Scottyb! Site sponsors ROCK!
