As above my s2 rst ones shagged wonder if it's worth having it repaired or just buying another 2nd hand one they seem to be going for about 200 now?

Thing is if a repairs the same sort of money I'd be inclined to go down that route the diff is still ok just noisy bearings

I see a CTS stage one is 695 but is that exchange?

 

If its just bearings, repair it yourself. Not difficult if you have access to a press

 

I do have a press but last time I took a box apart it never went back together
