I've got a squealing roller on my under carriage. I think its a front one. I've never had to replace any under carriage parts so before I do, what are the dos and donts of replacing under carriage parts. the operation seems fairly simple, but any tips or tricks are much appreciated. And also a supplier. I don't care much for my local bobcat dealer.
Have you checked the idler for play (slop)... you will probably need to remove the track completely! I use 2inch round pipe between the cogs so you can slide the track over the front idler and drive cog easier
