Krome_Dome Posted September 21, 2014 Posted September 21, 2014 Hey guys, I recently picked up an 86 4x4 v6 MJ. Whenever I throw it in 4H and turn either left or right there's a violent knocking. I have no idea what it is and would appreciate any input. This is my first 4x4 vehicle, I don't know much about 4x4 at all. Lol.
thejim42 Posted September 21, 2014 Posted September 21, 2014 Does it feel like the wheels are hopping when you make tight turns? Or do you hear a popping noise?
Eagle Posted September 21, 2014 Posted September 21, 2014 Are you putting it in 4WD on pavement? If so -- DON'T!
Krome_Dome Posted September 21, 2014 Author Posted September 21, 2014 Does it feel like the wheels are hopping when you make tight turns? Or do you hear a popping noise? No it just sounds like a violent knock. Are you putting it in 4WD on pavement? If so -- DON'T! Duly noted. Why not though? I'm just essentially putting power to all four wheels. I just wanted to test out the 4x4. Do you think it wouldn't make those noises if I was off-road?
88ComancheMitch Posted September 22, 2014 Posted September 22, 2014 IF you're off road you allow some minor slippage when the tires are moving at different speeds, like when turning. On pavement it's very hard to turn wheels at different speeds because the tires are gripping, usually causing a "hop" and such when turning. Hope that helps.
thejim42 Posted September 22, 2014 Posted September 22, 2014 How big are your tires? And are you running factory or aftermarket wheels?
Incommando Posted September 22, 2014 Posted September 22, 2014 You cannot run a traditional part-time transfer case like the 207/231 that came in our MJ's on dry pavement. It puts the case in a bind when you turn. You can do this with an all wheel drive or "full time" case as they are designed for internal slippage to compensate. You really should google up some basic 4wd info and read up on it as it will probably help you in the long run.
Krome_Dome Posted September 22, 2014 Author Posted September 22, 2014 How big are your tires? And are you running factory or aftermarket wheels? I do not know the size of my tires, I believe they are about 30 inches. 235/75/15 If memory serves me. I'm pretty sure they're aftermarket wheels, but not 100% positive.
