My pinion seal is leaking. I have a bad grinding sound coming from my rear differential. I was told if I drive it anymore the rear end will lock up. Is it ok for the truck to disconnect the rear drive shaft and drive it with 4wheel drive? I have 109 miles to drive it on dry roads. (Highways and back roads.)
Do you
have the same problem?

Diff will still be turning via the axles, so taking the tail shaft out will not help much, only that the dill will not be under direct drive load, you can give it a try, but keep a close watch on diff oil temp and noises.

ARE YOU STILL UNDER ANY SORTA WARRANTY?

SOUNDS LIKE YOU NEED TO LOCATE ANOTHER (MAYBE USED) REAR AXLE ASSEMBLY WITH THE SAME GEAR RATIO

EVEN A BACKYARD MECHANIC COULD PROBABLY SWAP IT OUT IN (BEING REALLY GENEROUS) THREE HOURS OR LESS (PROBABLY LESS!)

A DIFFERENTIAL LOCKING UP WILL "MAYBE" EXHIBIT "SORTA" THE SAME ALMOST DISASTROUS RESULTS AS WHEN MY REAR OUTPUT SHAFT ON MY TRANSFER CASE LOCKED UP ON MY '77 JEEP CJ-5

......I'M SPEAKING OF THE REAR WHEELS FAILING TO TURN, ALL OF A SUDDEN AT 55 MPH
