OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Victa Lawn Mower Frames Victa self propelled mower problem

I'm new here so I hope I've picked the right forum. I have a VSX160 powered self propelled victa that is about 3 years old and one wheel is not driving. I've searched through these forums but I can't seem to find a relevant post. I'm guessing its an easily fixed problem but with no workshop manual I don't know where to start.

Any suggestions welcome
Thanks

With no answers I've had a closer look and it seems like the problem is in the rear gearbox/diff? that sits inside the frame next to the rear left wheel. I can hear something slipping/missing inside when I turn the left wheel- but the right one is fine. Gearbox is made in france but I can't make out the brand.

I'd take it out- if I could work out how to get the rear wheel drive off. I can get the wheels off fine- but then what? I can see a spring on either side that appears to hold the whole mech up?

The springs look like what I call "sproings"- because they'll go sproing and vanish if I try and remove them
