i have 2 Detroits, front and rear in my 1989 LN106 hilux which is my DD , i bought them in 1994 and the rear one has done 440000kms never had a spanner on either except to change crownwheels the rear is on its 4th from memory , on the road they are great tyre wear is not worth worrying about as I used to run BFG mud Terrain s in 32 x 11.5 and I could get 100000kms out of a set of 5 but that was in the 1990s to early 2000s the tyres now only last about 70/80000kms like my last set of Cooper ST , the only thing with Detroits is that they rely on the friction between the tyre and the road to work , if there if no friction the Detroit will lockup and stay that way until sufficient friction is encountered , I have had the rear break loose numerous times and the back steps out on a corner ,no problem if you are aware of it , just apply opposite lock and keep going , have driven in snow but not encountered ice , in snow about 3 inches deep on a dirt road have had the rear break loose in 2wd whilst accelerating and the turbo getting on boost
ARB air lockers when locked create more tyre wear and if the o rings in the piston leak or fail the locker doesnt work and you can get the smell of EP gear oil from the compressor
