- 1997 mountaineer
I'm new to this forumn and have already done quite a bit of browsing the archives, but still have a question. My 97 mountaineer needed a rear Diff pinion seal replaced. I have gotten the old one out and the new one in. I understand the torque adjustments, bearing preload, etc....however when replacing the companion flange I am at a bit of confusion...Now it took a puller with quite a bit of grunt to get this thing off, so it only seems to me it takes quite a bit to get it back on... but in several procedures I have read the following
Rear Axle Companion Flange Installation
1. Apply a small amount of lubricant to the rear axle universal joint flange shaft splines. Align the mark on the rear axle companion flange with the mark on the drive pinion shaft. Install the rear axle companion flange using Companion Flange Replacer TOOL-4858-E or equivalent.
2. Install a new pinion nut on the pinion stem.
3. Note: If a new rear axle companion flange is being installed, disregard the scribe mark on the drive pinion shaft.
Note: The rear axle companion flange must never be hammered on or installed with power tools.
My question = This flange does not just slide on nice and easy, it takes quite a bit of grunt to get it back on, and obviously I dont have this TOOL-4858, what the trick?
I saw one post that mentioned taking it off and putting it back on using an impact wrench. Can one use an air impact wrench at its lowest setting, with using the pinion nut to get the flange back on? then as it nears bottom finish the torque with the manual torque wrench? afterall the avg torque is 160 ft lbs before taking rotational torqe readings.
Sure would like to finish the project but dont wanna make any mistakes.
Many thanks
