Is it normal for 4 Wheel Lo to clunk on pavement?

Question

Especially when the wheel is turned or reversing. I have a Eddie Bauer 4x4 1999 Explorer.

Answer 1

Yes. Most 4wd systems lock up the front wheels in low and are only meant to be used in that mode in snow or slippery conditions that allow the tires to slip a little in relation to each other and rotate at different rates like when you are turning. If you use low gear on dry pavement, the tires have full traction and can't slip which causes the axle components to bind up giving you this clunking noise. Had the same problem when I was a novice plow truck driver only with a Chevy 2500.
4WD should not be used on dry pavement especially while turning and can cause damage to your drivetrain .

Answer 2

When in 4 wheel low, you're putting tremendous amounts of torque on your CV joints. This is most likely what you're hearing clunking. Try to avoid using 4-lo on dry pavement, especially if you're doing tight maneuvering. It is mainly designed for off-road use, or possibly pulling a REALLY heavy load (like pulling someone out of a ditch.)
Hope this helps!

Answer 3

O boy you have a problem. the knuckle is going bad don't go into 4 wheel unless you need it and never over 45 in this condition I have same problem just use it when needed but I have F150 4x4 they are not cheep. they say going into 4 wheel at different speeds keeps them lubricated but its too late for you and me. keep it simple or shell out cash now.

Answer 4

Don't use the 4 L on dry pavement. It isn't made for that. You will do some damage to the drive line.

Answer 5

yes, my 06 f150 does this as well as my 1989 F150. this is mearly the front and back wheels pulling and going at different ratios. it is normal. dont run 4x4 on dry pavement also.
