I have a JDM 91 Land cruiser with the 1hdt it is full time 4 wheel drive with a single locker switch. I have differential fluid leaking to the Knuckle on the drivers side. I see lots of kits out there but, are any clearly better? Just looking for people that have done this repair and their experience. I would definitely not want a do over when there is vast knowledge on this site. Thanks for the great posts here!
