Lost a tire(shaft and all)

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&viewitem=&ru=http%3A%2F%2Fs earch.ebay.com%3A80%2Fsearch%2Fsearch.dll%3Ffrom%3 DR40%26_trksid%3Dm37%26satitle%3D220201378026%26ca tegory0%3D%26fvi%3D1&item=220201378026

Well I took it out for the first time on Saturday and beat it around a little. Mild trail climbing ect. It performed great. I decieded to take it to work on Tuesday to show it off and on the way home I lost the passenger side rear tire (axle shaft and all).

Any Ideas on what could've happened? Could I have broken the retaining clip while wheeling. Should I not drive 60 on the highway with the minispool in the rear?

Thanks

Sounds like the wheel bearing was bad.

Welcome to the "I had a bad wheel bearing in my Dana 44 and the axle departed the vehicle" club. Do a search for wheel bearing failure or something to that effect and I'm sure you'll have plenty of reading. There can be a lot of reasons for the failure such as a bent axle shaft, lack of lube to the bearing, water in the diff fluid, etc. However, there is no retainer clip on a Dana 44. It is all held in place by the retainer plate that bolt to the brake backing plate. If the bearing disintegrates, the shaft will go past the plate.

Exactly. AFAIK, we don't have C-clips on our axles. (from the factory, anyway.)

Yep, the bearing went bye-bye. We had the same exact thing happen while towing a 3500lb boat. Wife was sleeping when it happened and had a very rude awakening!

see my post on burnt fluid....

Basically jack up the axle, grab the wheel and any motion which results in a bang or echo... means something loose.

Last time my bearings were looked at was in 1986 @ 110Kmiles.....

I've always jacked the vehicle up, supported it with a jack stand, then tried to move the tire either vertical or horizontal(front to back), if their's any 'slop' then you've got problems brewing. I think a SMALL amount of in-out movement is normal. I hadn't checked our bearings in a long time, and would love to know how long we had whisps of smoke following us. I even remember saying something smells hot, and figuring it was truck brakes (we had come down a long grade). When I retrieved the axle, the bearing was very loose and the inner race had worn a deep groove in the axle shaft. I'm lucky it didn't mangle the WT flare on it's way out.

Well it sounds like you are going to be replacing one, so you might as well replace both.

At least someone didn't pull up next to you at a stop light and say your rear wheel was on fire....not that I would know anything about that.

Or someone else's body. When the right axle/brake drum/tire exited the J4000 on the interstate at 70mph, it traveled across a grassy center median and launched about 5 feet above the northbound lanes. I shudder to think what that would have done to a car and its occupants.

Luckly it fell off while I was coming up to a stop sign and I was less than a mile from a tire and brake shop. It's still sitting in their lot.

Are you sure it didn't snap the axle shaft? The ebay description says it has a minispool in the rear, which, besides a drag strip, aren't meant for the street. It may have bound up and snapped the splined end off the shaft.

There was about 2 1/2" of spline on the end of the shaft and the end was flat so I don't think it snapped.

Never had a locker before. How do you get from point A to B with one without damaging anything?

Mini-spool is not a locker. It is a locked. Something has to give. If the tires do not lose traction than something is stretching until evential failure.

A locker, simplified, locks and unlocks. Hence the clicking in a detroit LOCKER while turning.

A mini spool = Welded diffirential. Unless you on dirt roads day and night something will give. Sorry for your loss, at least no one was hurt.
