Default Loud pop in rearend

While on a trip to Mackinaw Island this week I was letting trike back down a small grade in a parking lot .the engine was off , in netrual and I heard a loud pop it does it every time I back the trike up running or off makes no difference It pops everytime it makes a belt rotation does fine going forward drove it over 1000 miles back home without having to backup but it still has the pop when I backup ...any help with the problem solving would be a great help .Thanks

Have the belt & sprocket alignment checked. The belt may be trying to climb the sprocket Also could be something getting caught one way in the belt.

Does it only do it when you apply some rear brake? I was getting a bad noise when letting mine roll back, either free wheeling or in reverse. It was a rear rotor that was hanging up. Mechanic just had to clean the mounting pins up and lube it a little and problem solved.

the sprocket the belt runs on has ALOT of side to side play in it . I guess I will tear it down and see if the isolation bushings have come out . Not looking forward to this job any tips to ease the pain is accepted.

Very possible the isolators are worn out. But seems that would pop both ways.

Last summer, the bearing in the sprocket failed on my 2012 triglide. A symptom of the failure was excessive side play in the sprocket, and when I put a pry bar to it, there was a lot of up and down movement also. As a direct result of this bearing failure, I lost the bearing fit on my differential. To fix it, I had to pull the body, pull the axles out, remove the rear end, buy all the bearings and seals, a new rear sprocket, and a new differential. I did all the work myself and saved a bundle of labor costs.

I believe that the cause of all the problems was that the $1.00 snap ring that retained the sprocket broke and everything else was a chain reaction to that failure.

I found that Surdyke had the best price for me on the sprocket and differential. I got the best price on SKF American made bearings and seals on eBay.
