Squeaking noise on a New Holland TC29D

[PDobson]

Hi, I have a 2006 TC29D, it has developed a squeaking noise when running at minimum 2000 rpm and higher ground speed in both 2 and 4 wheel drive. In lower gears and slower ground speed, no noise. Thanks in advance for any suggestions, I have greased the front axle and have checked the fluid levels in the front axle and each front hub.
I tried to attach a video but not able to, any suggestions on that would be great too, thanks.

Welcome to TBN.

A video would be helpful.
Is the squeak coming from a specific area?

 

[PDobson]

Thanks, sounds like coming from the front of the tractor. Can't tell for sure if from the engine or front end.
Didn't think it was engine related as is only make the noise when moving.
I have tried multiple times to attach the video and also paste it in, get a message that the image file type is invalid file. Any help on this would be great, thanks.

Sounds like it is probably the 4WD driveshaft rubbing on the shield.

I hadn't thought of that, but a very valid point to check.

Thank you both for the replies, you will excuse my lack of knowledge on this. Where would I check for it rubbing on the shield? Not finding any videos or diagrams to assist with the location, thanks.

I think I was able to get the video to load of the noise, thanks.

Have you greased the zerk on driveshaft between transmission and front axle?

Strange "squeak". Sounds more like a plastic squeak, but can't define. Does it occur the same way every time as in the video? Could jack up all four tires off of the ground and try again.

In either 2 or 4wd, the driveshaft turns in the cover from the dropbox at mid-tractor

Thanks, thought I did, will get back under it and check.

I know, thought it was an air "squeak" at first, yes it does occur similar to this but when I put it in high range with the faster ground speed it is more frequent. Will get back under it and look at things.
Might need some heavier duty jacks and stands to get all 4 off the ground.
Thanks for the reply.

Almost sounds like some rear tire tread is hitting the rear fender well?

Grease the front axle center pivot. There may be two grease fittings, one in front and one on the back of the axle. If that turns out to be the source of the squeak then check that its not worn.

 

[PDobson]

Thanks for all of your replies. I went under and added more grease to the zerts fitting on the front axle shaft shield. I had greased it, but added 10 more pumps and all good, no more noise.
Your inputs were great and got me where I needed to go and get it corrected. Thank you!!

Nothing worse than not knowing where an odd noise is coming from!
