Driveline Noise/Whine

2008 Nomad 1600 with 83,000KM (Approx. 50,000 miles)

I noticed a noise about a month ago that seemed to be coming from the front wheel. Installed new front wheel bearings (All-Balls) about a week ago but that did not correct the issue. The old bearings looked pretty good according to the shop that knocked them out for me.

I attributed the noise to the front tire, a Dunlop E3. No idea how many km on the tire as it was on the bike when I bought it about 15 months ago. Still a fair bit of tread left, but some cupping is starting on the LH side of the tire.
Thinking it was just the tire, I figured I could live with it until I replace it.

However, last night on the way home from a 2 hour ride I noticed that the noise was louder and become a very loud whine when I let off the throttle. When decelerating, if I pulled in the clutch it would quiet down. Also noticed the whine briefly when releasing the clutch when upshifting.

I checked tire pressures and both engine and rear diff fluid levels this morning and everything is up to par.

Based on searches of previous posts, I suspect either U-Joints, Drive shaft or the bevel gear bearing. Maybe rear wheel bearings? Any suggestions on where to start looking?

I'll have to tear into it next week when I get back from vacation. Planned on taking the bike but that idea is now out the window.

My guess is the drive shaft u joint is on its way out and some recent posts described a tear down of the bike to get at the drive shaft.

Sounds like the bevel gear bearing to me. I just swapped a 1600 into my 1500 nomad for a bad bevel gear bearing and bad 2nd gear that would jump out.

Thanks redjay. I'm back from vacation and I'll make time this week to tear things apart and see what seems to be the issue.

I agree with Brock. Dump the oil and look metal shaving. Make sure you pull the screen.
