After just a short test drive, the pinion on her Dana 35 was much warmer than the rest of the axle.  Listening with a stethoscope confirmed that the pinion bearing was noisy.<\/p>\n<p>I tried just changing the outer bearing and seal but since the race was worn was well, I had to disassemble the differential and change both the pinion bearings.  <\/p>\n<p>I ordered a Pinion bearing kit from Crown Automotive.  This kit came with bearings, a new crush sleeve, shims and a reusable gasket.<\/p>\n<p>I removed the wheels, and brake drums. Then I removed the cover and drained the fluid. Next I removed the carrier. I was careful to keep the bearing races and shims in the proper order. I noticed that the bearing caps were marked with and X to keep them on the correct sides.  One X was vertical and one was on its side.<\/p>\n<p>I dropped the drive shaft and removed the pinion nut.  I used a dead blow hammer to knock the pinion out of the front bearing.  I then used a pry bar to remove the pinion seal.<\/p>\n<p>I used a chisel to tap out the two bearing races. I used a soft punch to drive the in the new bearing races.  I used a bearing separator and hydraulic press to remove the inner bearing from the pinion. I ended up breaking the bearing race while pulling it off, so I was glad I was not trying to reuse it.  I reused the shim under the bearing. I used my heat gun to warm the bearing and then slipped it onto the pinion shaft.<\/p>\n<p>I installed the new crush sleeve on the pinion as well.  Next, I cooled the pinion in the freezer for a while before slipping it in to the housing and placing a warmed outer bearing on the shaft.<\/p>\n<p>I installed the seal and yoke and then tightened the pinion nut until the preload on the bearing was about 15 inch pounds.  To check the preload, I had to use several adapters to get from the \u00bc inch drive of my torque wrench to the \u00bd inch drive of the socket.  <\/p>\n<p>With the preload set, I reinstalled the carrier. I used a dead blow hammer to tap the bearings into place.  I reinstalled the caps making sure they were turned the right way round and they were on the correct sides.<\/p>\n<p>I slipper the axle shafts back in place and re secured the C clips. I then reinstalled the center pin set screw.<\/p>\n<p>I put the cover back in place using the reusable gasket from the kit. I put some silicone on the cover to glue the gasket to it and cleaned the housing well. I put the bolts back in and tightened them evenly.  I filled the housing with gear oil and the <a href=\"http:\/\/www.jdoqocy.com\/click-3340827-10711125?url=http%3A%2F%2Fshop.advanceautoparts.com%2Fwebapp%2Fwcs%2Fstores%2Fservlet%2Fproduct_x_7070977-P_x_x%26nAID%3D11138&#038;cjsku=7070977\">Limited Slip friction modifier compound.<\/a><\/p>\n<p>I reinstalled the brake drums and wheels before taking it for a test drive.
