Hi gang,

My 25 yr old 1989 Dodge PowerRam W100 4x4 truck may need the front wheel bearings re-packed and overall re-lube....What would it sound like if the service is needed??
Any recommendations, techniques recommended for proper procedure??....What about the front axle U-Joints near each front hub??..Any recommendations for proper maintenance of the U-joints??

I do NOT have a Chrysler Service manual for that year model. However, a HAYNES manual can be purchased. Is it (HAYNES) worth it??

Thanks!!

It would be a not normal noise coming from the front end, almost like grinding. It would get worse in a turn. Left turn - more noise from the right hub. Right turn - more noise from the left hub. You can pack them by hand, but I don't recommend it. Very messy and hard to do. Take the bearings to a independent shop and let them run it through their packer.

U-Joints - check for slop and missing pins.

Haynes is worth it.

Hello, I also have a 1989 Dodge, mine is a W150 4x4 - - - worn wheel bearings, or dry ones, which will wear quickly, sound like a low whirring or growling sound; jack up the tire off the ground and see where any wobble might be coming from (play), and whether it is in the tie rod ends, or the wheel itself; also check upper ball joints to see if they have play. If it has been a very long time since they were lubed, it is a good idea to repack them with wheel bearing marine grease, which is the blue-green water resistant grease. Clean the bearing races off and look for scoring, either on the races or the bearings, if so, they should be replaced. U-joints worn usually have a clunking noise, especially when turning on front axle; and check them for play as well. Let me know if that helps. - - Lance; Rockford, IL.

Thanks to all for replies!!.....I am so new to this procedure...The HAYNES manual has a pretty good description but not enough pictures to depict the precise procedure of removing/repacking the bearings, seals, etc..... Troublemsome for me since I am so unfamiliar with the terms (nomenclature).

I did do the HORIZONTAL and VERTICAL "tug" on the front tires and very little play, if any, was detected. That tells me the bearings are still "tight".....Also, the ball joints are in good shape....Do you think it's OK to "keep on rolling" for awhile until I get a good Mopar Service Manual??

The truck has never been abused and as mentioned before, the 4X4 had never been used until I purchased the truck...I have changed the front and rear differential fluids and also the transfer case fluid.

Thanks for all help and if anybody has additional pictures, book clippings, etc. to share, it is GREATLY appreciated !!

You'll probably be ok for a while, Mike. Just don't let it go too long without at least having a shop take a peek at it.
