Ok, last week i took my truck out for another test run and I got going down the street and drug it a little ways and aired it back up then it started making a horrible noise and vibrating like hell. So I got it back to the shop and I was looking for what it was and my mid dhaft bearing was coming apart. What do you think could have caused this? I was going very fast and I probably didn't even go a 1/8th of a mile. Could it have just needed to be replaced. Another thing thats happening to me is the tranny(auto) is very hard to shift from park to the other gears when it's aired down. I don't wanna have to replace my transmission next I'm pretty much broke because of my truck now. I need help quick! I've already ordered the new bearing and it will be here tomorrow.

 

Sounds like your link setup is pushing your driveshaft into the carrier bearing, which in turn is pushing the first shaft into the transmission. The carrier bearings are only meant to move about 1/2" forward and back. If it is moving more than that it will wear out quickly, or tear itself apart. Your cheapest fix is going to be putting a slip spline in your driveshaft. Costs around $150 or so, and it will save you replacing carrier bearings every few months, and it will also save your transmission. If in fact it is pushing into the transmission, dragging it will be putting a lot fo strain on the internal components.

 

Where can I find a splined driveshaft for my '92 2wd X-tra Cab?

 

Fidn yourself a junkyard or recycling center with some yotas in it. Its amazing the parts you can find! Whats wrong with yours ?

 

What years/models?

Nothing is wrong with mine, yet But what years and models would have a driveshaft i could use on my '92?

 

Anything between the years of 89-95.5 that have the 4cy engine & the same transmission that you have in it now. The automatic drive shafts are shorter than the manual.

By the word "anything" do you mean any 4x4?
