i have a detroit auto locker in the rear. no maintanance, no special oils, it just works. it does take a bit of getting used to for suburban driving, but after that all good
I totally agree jacnden. Had a Detroit in the back of a Troopy years ago. As you say there's a few little quirks with suburban driving, but mine was a few series ago.
If they were available for my vehicle when I purchased my air locker, Detroit would have been the winner.
