Four Wheel Drive Problem

Post by 14x4 »

Every time I take a sharp turn while in four wheel drive, it feels like something behind the front wheel is grinding - particularly on the driver's side. Not only can I hear it, but the car actually stutters and slows down while turning.

Could this be because my front end is lower than my back end? (I installed the Boise spring kit but I haven't adjusted my torsion bars yet - my truck is not even.)

Anyone have any ideas? :?


Thanks.
Mike.

You should never turn hard on a hard / good traction , surface while locked in 4x4. There is no where to give.

Ok, that said, could it be that your hearing a partially engaged front axle shaft?

Maybe the bind putting pressure on a weak bearing? Could the sound be a brake rubbing due to the loose wheel bearing?

Could it be a frame rub or body rub you are hearing? The frame rub will vibrate things pretty good and can sound horrible.

I suppose I have to consider all of those things. The only reason I've been using it is because it has been raining on and off for about a week and my tires are pretty bald. Every time I go even slightly uphill from a dead-stop, my tires spin.

Use less skinny pedal. Sharp turns in the rain almost always break my trucks rear free and that is with good tires.

No fix for bald tires, but airing down might help a little.

I'm not worried about my current junk tires because my 33's are at the shop waiting to be installed. I'm just worried about that grinding. :?


Does adjusting my torsion bars and adding the front wheel adapters have any chance at fixing this problem - whatever it may be?

I don't think the tire rubbing against the body or frame would make my truck stutter like it does (although I could be wrong - that tends to happen alot :wink:). It feels much more serious; like something is stopping the wheel from spinning or something.

The front and rear axles are joined through the transfercase, but unlike the way each axle is joined by the differential, there is no differential to allow the front and rear drive of the transfer case to turn at different rates like the differential allows the axles to do.When you make a turn something has to give. On lower friction surfaces you do not feel the scrubbing and slipping that occurs. On a high traction surface this can be very violent. Tires slipping is a good thing. Breaking CV joints or axles can happen too.

AWD transfercases have a clutch pak to allow them to work on traction surfaces. Ours do not have this. They are directly connected, no where to give when the front and rear axles are turning at different rates such as occurs in a turn.
