M1009 differential

[airbornebandsman]

Hey all,

My M1009 started having what I thought were some transmission problems last week. It felt like the rear was dragging or having a problem getting going and then it started slipping a little after that but only on starting off, and once or twice when making a right turn the right rear wheel locked up but when I turned straight it unlocked. when I took the pumpkin cover off (to replace seal) there was no fluid in there. the gears in there seem to be loose but I am not familiar with that area of the vehicle. Could all this be caused by no fluid or might it be something else?

well just a guess but no fluid is not a good thing. It could be messing up the locker. If you have had problems I think adding fluid wont help you out that much. I think its time for some new gears and bearings. you can get NOS rear ends for about 400 bucks. That would be the best way. Try www.colemans.com

But before you go...... Many,many,many years ago my father's '65 Belair got a lube job and they left the plug out. He drove it, billowing white smoke going down the highway. As a seven or eight year old i thought it was cool. The old man was not so amused. But he had it towed and re-filled and a new plug. We drove that car at least another 100,000 miles after that, the bearings in the axle singing opera the whole time. Fill your's back up and try it. All you lose is the cost of a few pints of ninety weight.

I've got used diff's that I pull the covers and check gears etc.. shipping might be an issue but for $200.00.
