I experienced a problem with my 09 Prowler jerking when you try to take off from a dead start or at a rolling start. It did not do it when in 4 wheel drive. I discovered that the rear driveline was turning as much as 3 or 4 revolutions before rearend would engage. This machine has the turf saver rear differential. I removed the rearend and found that the spool was welded so you could not take apart. I ground the welds off and dissassembled and found that there are a type of clutch pack on each side. Mine was damaged beyond any repair on one side. So to make a long story short I was wondering if anyone has removed there limited slip differential and installed a spool from a older model. If so do you have the correct part #'s. This gear assembly is upwards of $700.00 everywhere I have looked online and the comparable older gear/spools are around 150.00 in the older models. I have compared the parts diagrams and numbers to several other models and everything seems to be the same except for the pinion tooth numbers and the spool with the ring gear. My pinion is 10 tooth and the ring gear 36 tooth. I can't afford to spend 700 plus dollars to repair this rearend so any help would be appreciated.
