Clunk in right rear

Sun Feb 15, 2004 9:42 am

Hi there! I'm new to this forum, but have been reading messages and comments for about a month. I recently bought a 49 farmall cub and have a question I'd like to ask. There is a clunk in the right rear. With the tractor jacked up and the tires just clear of the ground, and the tractor in gear, there is a clunk as the wheels rotate. With the engine off and rotating the wheels manually, I get the clunk. I took the wheel off and rotated the hub and I do not get the clunk. Any suggestions? Thanks in advance, Bob

If you are lucky it was or is nothing more than loose lug-bolts or loose wheel weight bolts. :?:

Bob: Try reinstalling the wheel and tighten the lug bolts securely Also, check the bolts which attach the disk to the rim. Loose bolts in either location will produce a clunking sound as wheel rotates. Dan

Thanks for the replies. I did tighten the lug bolts but that didn't help. Dan I did not check the other bolts as far as tightening, just eye-balled them. I will take your suggestion. Thanks for the help, Bob

Bob, if it clears when you remove the wheel, and tightening the wheel, disk, and wheel weight bolts doesn't help, you may have a bad bearing, or possibly a chipped tooth on one of the gears. Removing the wheel could be taking enogh weight off to keep it from being noticeable.

If the wheel and tire (assembly) is off the hub and there is no noise and you tighten the entire wheel to rim bolts, I would say (maybe) you have frozen moisture (ice) inside your tire.

Try putting you ear as close to the tire as you can when the tire is rotating off the ground and maybe you can hear movement inside the tire.

John, Thanks for the hint. With the wheel off I wasn't able to get the clunk. Makes sense about the weight. It gives me another possibility. I appreciate that. Bob

Maybe a disc to rim bolt loose but rusted so you cannot turn it. Same on the weight bolts.

Thanks to Dan England, johnbron, John *.?-!*, John Fowler, it appeared to be the bolts that attach the disk to the rim. They looked tight, but all were loose. I tightened them and checked both with the wheel jacked up and turned manually and with the tractor on the ground and running back and forth. Thanks alot to all that contributed. I'm ready to mow, that is as soon as the snow and ice leave. Bob

Thanks Jim Hudson, you hit it on the head. Bob

Bob, Been there, done that! :D In my case it was an A, but the same thing, loose rim on the center. It made a grinding noise so I figured it was bearings in the final drive, I had it jacked up and rolled the wheel around when I discovered the real culprit. :lol:

parts man, Thanks for the reply. It's nice to know I'm not alone. I'm also sure there will be other times that I overlook things. Thanks again, Bob
