Rear End Question
is it normal for these rear ends to break traction easily on wet pavement?
i have noticed that unless i baby my throttle of the line i will be spinning the tires.
i really have to be careful when making turns and getting on the throttle from sitting at a stop light. when turning it is always the inside tire that breaks loose.
i have the full-floating sterling 10.25 limited slip.
thanks for any info.

'92 1/2 - '94 IDI ip fuel economy killer screw
did you adjust your torque screw on the ip? if so,sounds like you could stand readjusting it,so she's not dumping in so much fuel all at once.the fuel economy will suffer greatly setup like that.what you want is to start out with the least amount of fuel possible of course for economy,but you don't need to go so drastic, to keep some off the line performance.just enough so your not dumping fuel at all once making for such a touchy throttle that the tires want to slip wasting energy from the fuel,not moving your forward.
on a side note,sounds like you have your E40D setup good and the converter is still in good shape.

nope. have not touched the torque screw or the fuel screw under the triangle cover on the IP.
nor have i done anything with my tranny or tps. lately though it does seem to get up to speed a little easier without so much throttle input.

oh man, if i really wanted to i could drift around corners so easily. might not be pretty but could be done..............................wet pavement of course.
on a more serious note, the breaking traction sounds normal?

The EXACT same thing happened to me about a week ago. I was turning left at a light from a dead stop, went to shift to 3rd, and the next thing I know I'm sideways. It was an ***-pucker moment for sure. I chalked mine up to a few things:
1. The truck is still new to me (as is diesel and all that low-end torque), so I'm still getting used to how much throttle to give it in different conditions.
2. The tires have seen better days. Saving the pennies now to get a new set soon.
3. There was a light rain that day.
4. No limited slip.
But yeah, I would say it's all normal. There's no weight back there, and E-rated tires aren't really known for exceptional grip.

If you think it's bad in wet weather, try it on ice! You'll have the same problem in reverse trying to stop hard and locking the rear tires.
Yeah, the weight is a good idea. I used to put 500# of tractor weights in the truck bed for winter, just behind the axle, to aid with traction. Ditto when I pull loaded grain wagons (which don't have an tongue weight because they are four-wheeled).
I also suggest running less tire pressure when unloaded to increase the tire footprint. If you have the max sidewall pressure, that's for a max tire load and your tread footprint is about the size of a silver dollar with the truck empty. With only about 1/3 of the total weight of the (empty) truck on the rear tires, it' like you are riding on bike tires. I run as little as 28 psi but generally around 35 psi on my rear (285/70R16 radials) to allow for a light load. If I need to carry a full load, I air all the way up. If you have smaller tires, you will need more pressure than bigger ones (remember it 's the volume of air in the tire that carries the load and a bigger tire has more internal volume so needs less pressure to carry the same amount of air (by volume) as the tire with less internal volume)

PLEASE ENSURE you restrain them from sliding/flying forward in case of quick (or instant) stops ...
