Hello guys. So I had a buddy drop his quad off for me to take a look at it. The first issue was the quad bogs really bad when he starts working it hard. I am assuming this issue is from all the insulation on the gas tank missing and it almost being out of fuel which would cause the fuel to boil? I am planning to top the tank off and see what If I can re create the issue. The other issue I noticed was that the quad was very hard to push even in neutral. So I jacked it up and spun the front tires by hand and they seemed to spin easy. Then I tried the rear and noticed the RH rear tire was very stiff to rotate and would not even spin when I started the atv. I tried in 2x4 and turf mode and AWD? So I pulled the hub off that side and found the bearing was shot and now the axle spins but the LH now spins intermediately and makes a loud popping noise the odd time then engages and spins then stops? And the front tires also always spin even in 2x4? I am very confused on what is going on here any help would be very much appreciated
