When I do a search for a replacement buffer the letters PYU are for a 95 k1500 is this a concern? I purchased a vss for a 1998 high milage Durango with RWABrakes. Does this 95 k 2500 have a speed sensor on the rear Differential as well as the transfer case ? or is there one on top of the transmission? I will replace the one on the tail of the transfer case first Im having trouble getting the plastic buffer snapped back in place. Any. experience with placement?thank you. I see the multitude of questions your trying to weed through so please forgive my inability to work one issue at a time[emoji223] Sent from my SM-J700T1 using Tapatalk
