I have a 3 year 4wd old hsp xstr pro with major drive issue.

I want to try and fix cheaply and then sell, so i can buy a real car.

Drives on right side is fine, but left side [ front and back ] is not working properly.

At low revs i have no drive at all on left side only. At high revs left side is driving at about 30% only.

I pulled gearbox / rear diff apart cleaned and cant find the problem.

Not sure what the problem is maybe gears or bearings.

Start simple.

Work back from the wheel nuts through to the ultimate drive.

Probably could be just a pin missing on one of the hex's where the wheel attaches.

Thanks craig. That did the the trick.
