Re: Opinions on detroit in D 30
From everything I read online the 95 YJ is the change year and has a one
piece axle and 297 Ujoints, her ujoints are deffinately bigger then in my 81
CJ7. As for set up and install kit, all gears are new and there is a guy up
the road that according to all in town is the gear install king, he charged
her $50.00 to put the detroit in the rear, of coarse that was her taking the
3rd member over to him, but I think he does them for about $100.00
Canadian.. We get one 6" snowfall a year so that isn't a consideration, as
for lockright she went through 3 of those in the rear end and finally went
to detroit. I've talked to her about a cable dissconnect on the front to get
rid of vacum.
