Noise on back axle - Pride Revo 4 Wheel Scooter

OP writes that the fix is this.

I fixed this problem; I pulled the wheel and removed the axle nut and sprayed penetrating lube around the axle and put it back together- problem fixed... I also took the rim apart and sprayed rust preventive on the inside of both wheel halves because water can get in there from washing the dog stuff off the wheels (yeah you know). I wanted to pull the hub and have a look but it must take a puller because tapping on it with a brass hammer did nothing. So make sure the axle nut is tight...

When you say end play on the axle, how do you mean? Have you jacked the car in the air and grabbed the wheel top to bottom and side to side and felt for play in the wheel? If you did and it has play, I'd say you're looking at replacing wheel bearings and not a trans (Diff) problem.

A grinding noise suggests a bearing at fault or perhaps worn pads on the brake rotor.

However, the clunking noise you mention could also point to a problem with the drive shaft or differential.

The first thing you should do is to get under the vehicle and try twisting the propshaft back and forth. If there's any movement this points towards a worn universal joint on the propshaft. A worn universal joint can cause a clunking noise - particularly when pulling away. The vibration caused by a worn universal joint can also damage bearings in the differential and also to the splined ends of the axle shaft.

You're also going to have to remove the wheel from where the noise comes from and examine the end of the axle shaft/bearing.

Noise coming from back on trailblazer - YouTube

Make sure the axle was installed correctly. If you didn't push the axle all the way in it's possible that it's not engaging properly in the splines causing your noise. Am I correct in assuming noise wasn't there before and started after replacing the axle? If yes I would start there. Make sure both inboard and outboard joints are all the way into the transaxle and the hub. Also make sure you torque the nut.

A clicking noise when making sharp turns, such as when backing up or turning through an intersection? CV joint. Look at the axle on the noisy side and there'll be a couple boots. One may be torn. Dirt and water get in there and wash out the grease and wreck the joint. Best place to start.

to possible answers
the axles are new and the cv joints mat be firm resulting in noise transmission through failing engine mounts ( unlikely but possible )
the tread pattern may be the cause of the noise especially if the tyre pressure is incorrect
Take it back to the shop and take them for a road test to see if they can find the reason
when drive axles have to replaced , it generally means that the front lower arms have to be disconnected so a wheel alignment may also be in order

get a second opinion from an accredited service shop that has experience on your vehicle
sound like the mechanics at Midas are just parts replace and see you as a sucker customer

Check vacuum canister on right side of
front axle and it's hoses ,for leaks

After that, go back to the transfer case shifter
vacuum sw

Remove the front axle vacuum actuator
& see if it is rusted, and not releasing the
right axle

if you hear that clicking noise whether going forward or backward,,it's most likely a bad cv joint on your axle going bad,,or bad. you'll need to replace the axle it's coming from. just have someone listen to the noise while you're going forward or backwards while turning the wheel in motion to determine which axle is bad! hope this helps!!
