    Posted: 25 Jul 2019 at 1:34pm
I'm looking to purchase a D-15 Series II from a neighbor.  It runs out perfect except a very loud whine noise coming from the rear end when driven in fourth gear. All other gears are good with no issues. It doesn't sound like a bearing, more like the bull gear on right side. Has anyone else experienced such an issue and ideas how to fix it?  Thanks

Pretty normal for any D15 to have a howl when run at speed in fourth, have a number of 15's and it'll get your attention when run in 4th if you have not done it for a while.
Still a good idea to check fluid in finals . . . .

Our series II has always done that since it was new. But as said above check your trans and bull gear levels.

I had to replace a bearing in the bull gear of 'Troy', D-14 #1. Replacing it was easy... mopping up the oil wasn't fun though OR the loaded tire....

The howl comes from the final drives, most of the time, drop the pans, and inspect, at least change the fluid...Wink
