When engage the 4wd. The front wheels lock up when I turn. My rear tires start to peel out just to keep the vehicle moving. To test to see if the 4w engaged, I switched to 4w at a complete stop and even threw it in reverse a few times. Still locks up in both directions while turning. Is this electrical or due to the extreme rust that has accumulated?

 

Mine does the same thing. When I turn at full lock the truck has to try harder to move and the back wheels drag. I think it's normal because when in 4wd and when you turn it puts everything in a bind because when you turn your front wheels are moving faster than the back ones my 4wheeler does the same thing thats why I never put it in 4wd on pavement. Hope this helps, Clay

 

Ive had a similar problem, the tires almost feel like theyre grinding right?

 

Unless you have posi diffs it should not lock up while turning

 

Are you doing this on pavement? If so that's your answer

 

I have limited slips front and back if that's considered a posi.

 

Sounds normal. Even open diff will bind a bit in a higher traction area while turning. Good ls front/rear will exaggerate this. Its not a "problem" that's just how part-time 4wd works.

 

nope posi is basically a solid thru axel if that makes sense when you turn with a posi rear end you would notice it would feel like its skipping hard on your tires i dont think they come in half tons anymore.... back in the day they did but everything now has open/ ls rear ends for that reason

someone else with alot more knowledge will probably chime in and it explain it 100 times better lol

 

Your thinking of a spool my friend.

 

I'm surprised you haven't broke a cv axle. You don't run 4wheel on a good traction surface!!!! Ask questions if you don't know how something works BEFORE you go out and just start cranking the wheel at full lock for the hell of it!!!!!
