rear - end failure??
Ok guys I have a 95 f150 with a 5.8l in it. It's my work truck and a damn good one too. It purrs like a kitten especially with 218,000 miles on the odometer. However today i was driving down the highway, I heard a loud clunking and I could also feel it in my feet. This was followed by my spedometer falling down to 0 and I had no power at all being transferred from the motor to the drivetrain. My first thought was damn the tranny went. However when I got out to inspect I noticed that one of the wheels was about a 1 foot more than it should be at this time I also see that the wheel itself was still attached to the hub and the axle was sticking 1 foot outside of the rear-end housing, it was draining brake fluid because it broke the drum brake in 2 when the rear end exploded.......wtf happened here? the driveshaft spins but nothing is happening in the rearend. Does this obviously mean that my rear-end is done for? if so what would be the most economical way to fix this? I have tools and am a sunday mechanic however I havent ever done anything like this.

What he said, you're just going to have to pull the cover off and see what broke. You could pull the axle the rest of the way out and see if the end broke off, bujt you need to pull the cover and inspect it.

broken axle
I had this happen to my 87' with about 230000 miles on it. Once I got the axle out, it was broken in two pieces(more like twisted in two pieces). Rebuilt the rear end while I was at it, replaced axles and put a positrac in it as well. Not real good for gas mileage but it is a pullin' son of gun now.
It wasn't a cheap project for me but you could probably get by for less without the bells and whistles.
Good luck!

Well I cant hardly believe it but i found a complete rear end at a salvage yard for 150 bucks with 120,000 on it. I think this has got to be probably the most economic route. Now i just need to make sure of the gear ratio and firgure something out for those drum brakes. I think it has the 3.55 gears but im not too sure and I never have messed with those old brakes? Anyone got any advice on this(cheap place to get drum brakes?
Thanks,
J

What is with these silly 8.8 rear ends *blowing* up after only 200k? I completely lost count of how many times i've heard people having this problem!

My old 86 failed twice, about 10k apart, first the spider gears blew to pieces, I limped it home with the broken gearteeth locking up the axle for a second every half mile or so, replaced the whole diff, then 10k later it was severely worn andpitted at the wheel bearings and pinion shaft, to repair it would be a thousand bucks easy. I installed a 9" in its place and never saw another problem on that side of things

One thing I forgot to mention - make sure the yoke is the same. There are two styles, the flange and the saddle yoke. They aren't interchangeable so look at where the driveshaft meets the pinion and make sure they're the same.
As far as brakes, drum brakes aren't hard to do. While you have it apart, I would just replace all the brake parts. Wheel cylinders, shoes, and if you have any broken springs, get a hardware kit as well. A haynes or a chiltons manual will help you replace them.

That's exactly what happened to my parts truck axle!
The 2 smaller spider gears, one slit in 2 and the other got shredded all around bald!
That was because of a burn out, abit to close to the side of the road, and being winter, lots of little rocks and crap on the sides, 1 wheel peel caught traction, and CLUNK!
Drove on it a few corners, clunking and locking up for a second and giving a nasty jerk to the truck every mile or so, or every 2 seconds when turning.
