1m diff problem
Hi, how can you tell of your diff is going to worn out or not?
My car had 51k km on the clock, had the car since new and mostly on highway driving slowly. A week ago I changed my subframe and diff bushings and they realize that the right side seal is a bit wet( moist) not dropping at all, so they ordered a new seal(only one in stock) and replaced the right side and changed fluid, then I drove the car to do alignment which is around 35km distance and realize the left side is leaking badly onto the exhaust. Does anyone know what is happening? The left side was perfectly dry, and after changing the right side, the left Is leaking badly Thanks in advance |

As to why all of sudden the left let go. It could just be coincidence or maybe whale changing bushings so new load could've been put in the halfshafts that made the 10 year old seal give out. This is a tough one. Sorry it happened. Luckily you caught before diff runs dry. |

How can you check or tell if the diff is done or not? Shall I replaced the left seal and see how it goes? Or is my diff worn out and require a rebuild ?

Is there a breather for the diff? Perhaps the breather is blocked? Diff fluid heats up when driving and creates pressure in diff and since you changed your right seal the left becomes the weak point. Happens with my defenders when axle breathers are blocked. Let us know.

Marking the position of the seal wouldn't make any difference unless the seal has some sort of position it needs to go in. The breather I'm referring to is a vent for the differential. If the vent is blocked or obstructed then once the pressure builds up in you diff from heat, fluid will leak from the seals that are weak/old. You said you changed your right side seal, now that seal is nice and tight and if the breather/vent is blocked then it'll cause the fluid leak from other seals. And if you change your left seal and the breather/vent is still blocked then the pinion seal will probably leak.

Glad you got it figured out I've read that the diff should be good mechanically until at least 70-80k miles, where some have reported (bearing?) failures in the shorter shaft/pump side of the factory GKN unit.
