noise in 4wd
Big snow storm last night. So I needed 4x today. I hear this noise from the front end which almost sounds like a bad wheel bearing, but it only does it with the front hubs locked. Any ideas? Everything seemed to be working properly. Thanks in advance.

My bet is a CV joint. With manual hubs, it would only be turning when the hubs were locked. Slide under the truck and check the rubber boots - if they are cracked, your CV joints are shot. Just replace the passenger side half shaft on my 93 4Runner - wasn't too bad.

My '90 4Runner had an intermitent problem after about 130,000 miles with noise from the front axle when I'd engage 4WD in extreme cold . I was told by 2 dealerships that it was the needle bearings and that, although it sounded like hell, it was not damaging to anything. I never did anything about it and sold it in 2002 with 205,000 miles on the odometer. The guy I sold it to said he took it somewhere and had it fixed.

Don't use too much grease inside the hubs, just a light flim is plently. Too much and it can gum things up and make them not work right.

Thanks for the great tips...I'm going to clean and re-grease the manual hubs and see if that cuts out the noise. It sounds like an old farm gate swinging back and forth!!! But only occurs at 50 mph and up.
