04 durango rear bearings
i have a 2004 durango with 9.25 rear diff. i have to replace the bearing on pinion and carrier. the kit i have has a new crush sleeve. does anyone know the torque to seat the bearing and crush sleeve?
INSTALLATION
Hope this what you were looking for.
NOTE: The ring gear and pinion are serviced in a matched set. Do not replace the one gear without replacing the other matching gear. If ring and pinion gears or bearings are replaced, Refer to Adjustments for Pinion Gear Depth Setting.
Install rear pinion bearing cup with Installer C-4308 (1) and Driver Handle C-4171 (2).
Install front pinion bearing cup with Installer D-129 (1) and Handle C-4171 (2).
Lubricate and install front pinion bearing.
Apply a light coating of gear lubricant on the lip of pinion seal. Install seal with Installer C-4076-B (3) and Handle C-4735 (1).
Install proper thickness depth shim (1) on the pinion gear (2).
Install rear bearing (4) on pinion gear (3) with Installer C-3095-A (2) and a press (1).
Install a new collapsible spacer (1) on pinion shaft. Lubricate rear bearing and install pinion into the housing .
Install pinion flange with Installer C-3718.
Install bolts into two of the threaded holes in the flange 180 degrees apart.
Position Holder 6719A against the flange and install a bolt and washer into one of the remaining threaded holes. Tighten bolts so the Holder 6719A is held to the flange.
Install flange washer and new nut on the pinion and tighten nut until there is zero bearing end-play.
With a torque wrench (3) tighten the pinion nut to 285 N·m (210 ft. lbs.).
CAUTION: Never loosen pinion nut to decrease pinion rotating torque and never exceed specified preload torque. If preload torque or rotating torque is exceeded a new collapsible spacer must be installed. Failure to follow these instructions will result in damage.
Slowly tighten pinion nut in 6.8 N·m (5 ft. lbs.) increments until the desired rotating torque is achieved. Measure the rotating torque frequently with an inch pound torque wrench (2) to avoid over crushing the collapsible spacer.
Check pinion rotating torque with an inch pound torque wrench. The pinion rotating torque should be:
Original Bearings: 1 to 2 N·m (10 to 20 in. lbs.).
New Bearings: 1.7 to 4 N·m (15 to 35 in. lbs.).
Position exciter ring on differential case. With a brass drift, slowly and evenly tap the exciter ring into position.
Position ring gear on the differential case and start two ring gear bolts. This will provide case-to-ring gear bolt hole alignment.
Invert the differential case in the vise.
Install new ring gear bolts (2) and alternately tighten to 157 N·m (115 ft. lbs.).
CAUTION: Never reuse the ring gear bolts. Failure to follow these instructions will result in bolts fracture.
Install differential in housing and verify gear mesh and contact pattern.
