95 k1500 wheel driver side wheel

[scottinachevy]

I was driving in my yard and I noticed that my rear driver side wheel does not spinout when I apply the gas hard. Only my pass side will. Is that a big problem and how do I fix this problem? THANKS

Unless your truck has a limited slip differential (posi-trac), this is completly normal.

Check your RPO sticker located on the inside of your glovebox. Every option your truck came with from the factory is listed there, each with its own code.

A "G86" code is for a limited slip differential. This is pretty self-describing...it won't prevent slippage totally, but will direct most of the power to the wheel with the most traction. These usually work with either a set of gears or clutches in the rear diff. If you have excessive wheel spin then it may be time to change the fluid and/or check the clutches for wear. These diffs usually take a special "friction modifier" additive in addition to the normal gear oil. Check your owner's manual for the correct fluids.

A "G80" code is for a mechanical locking differential. These pysically lock the two axle shafts together when one begins to spin faster than the other (~25 rpm difference). There is a special spinning shaft with weights inside the diff that uses centrifugal forces to activate the locking mechanism. If you are getting wheel spin here, this mechanism is broken or fouled up.

Good luck!

with one wheel drive this is the norm.

thanks for the info

yours is probably like mine, spins 2 in front and 1 out back. lol they should call it 3 wheel drive. if yours only spins one in front too, that should have posi, so i would see if i could get some positraction additive and put it in the diff up front.

you do not use positraction additive in the front dif...the locking actuator, locks the front axles together...

positraction by the way is an unlocked system..there is slippage hence the need for the additive,should you have the limited [useless] positraction..

I'll change my earlier statement slightly concerning the limited-slip diff...it is supposed to transfer power to the wheel with traction, but in reality only a small amount of power goes to it. A G86 limited slip diff is different than the G80 positraction or locking diff. So, putting a friction modifier in a locking diff is a waste of money. Check your codes and your owner's manual to determine what you have and what fluid(s) are needed. Here's a wiki on all the different types:

For a K1500 (4wd), you should have locking diffs in front and back. If both rear wheels aren't spinning on a slick road or mud, something's broke.

my 1996 impala ss has the limited slip positraction..on solid pavement it will burn out two even tracks rt/LFT...

ON ice going up a slight grade only one wheel will spin,,,the wheel on the ice...limited slip is not good ....

but driving an impala ss in the ice/snow is not very smart either...
