Ring and Pinion gears
 

My truck is getting up in the miles over 200k and I pull a 34ft trailer. Starting to get what I think is a lot of slop in the ring and pinion gears. Need info on who has good ring/pinion gears or should I look at getting a whole rear end assembly? Ive seen G2, Strange engineering, Yukon. Just had axle bearing replaced on both sides. Hopefully I can get thru the events I have to do and get home before the rear end blows up.

Strange is the best,but if the ring and pinion are worn out it should be humming and getting hot...Does it have those symptoms...BTW if the R&P is stock and its a 3500 DW,most produced were 3.73 ratio...
