i jus put a new yoke on my rear14bltff. i used a impact gun and didnt replace the crush sleeve. should i take it apart and replace the sleeve? i jus had the rear end rebuilt but the guys who rebuilt it put my worn out yoke on it....it seems find when driving but when ny rear end seized last time it was because my buddy who did the gears didnt set up the pinion right and the bearing wentt into the gears.....my truck will be seeing some freeway time. but the yoke seems like theres no movement....u guys think i should replace the crush sleeve and reset the pinion? or will it be good since the rear end was jus rebuilt abd had hardly had any miles on it.when i used the pmpact i turned the power/torque down on it...
