Thank you for this useful information. That makes a lot of sense. The feed line needs to be rubber-like to allow for flex as the rear suspension dampens and springs back up, thank you! Do you think I would be okay with cleaning this rear end, redoing the seals and letting her rip? I feel like the side gears and spider gears are worn but will be okay to run. Last thing I would hate to do is put it back together and then have to re-do it after it blows out. What would be your call?
