Rear end popping

[deubanks]

I have a Case jx75 and noticed the other day the rear end was popping when turning. Any ideas what would be going on. Oil levels or ok. Thanks

All bolts on the wheel is tight?

 

[Redlands Okie]

My first thou got also. REALLY REALLY REALLY tight. Torque wrench is handy

G'day is it possible the diff lock is partially engaged?

Redland are you talking about torqueing the wheel bolts? I will check all ideas when I make it home. Thanks for your input.

Check all the bolts and nuts on the wheels, including inner and outer rim areas. I had the same noise once and it was caused by an under torqued adjustable rim bolt.

 

[Redlands Okie]

Yes. All bolts and nuts on rim and wheels. They often times need to be torqued way more than one might expect. Check your specs for your equipment. They also need to be rechecked every once in a while

Not trying to scare you but my old '52 For 8N was starting to make the popping noise. I found out what it was when the hydraulic pump destroyed it's self. The popping could be felt through the floor boards and got louder and louder to thumping. The 8N has the hydraulic pump in the bottom of the transmission sump. I had changed the pto shaft/stub out because it was leaking fairly bad at the back. I didn't quite get the shaft seated where it needed to be. That was lots of fun finding another 8N hydro pump and rebuilding it to put in. I hate those self inflicted wounds. :ashamed:

Well I've tightened all bolts and everything thing is tight and the diff shaft looks like it is pulled out all the way. The popping is still there. Now what?

Jack up the rear of the tractor and see if the wheels are free to spin separately to be sure the diff lock is not still locked in! When turning are the rear wheels digging in more then before?

I had a popping in my 4240 sounded like lug bolts. I found out it was the front axle pivot was loose.

I want to tell it seemed like tires were digging a little more than normal, but I can't say for sure.

The diff lock foot engagement could appear to be released but could be partially engaged. The lugs on the diff lock could be rounded off semi-engaging the diff lock which would cause a knocking noise that is even and in cadence and rhythm to tractor speed.
As previously suggested, jack up tractor rears and see if you get opposing spinning.

took the tractor to dealer and findings were that the differential was cracked and needed replaced. thank you guys for all your help.

Thank you very much for the follow up. Too many times ppl post things here and then they disappear which helps no one beyond the conjectures. Follow ups solidifies the education for all involved.

Thank you, my thoughts exactly.
