i need to change the pinion seal on my 02 gt and from what i've read it doesn't seem difficult , but the only thing i have a question about is the crush sleeve.once i'm putting everything back together and i torque the pinion nut down to 140ft lbs ,that should not further crush the sleeve,am i correct?i plan on making marks and counting the threads so i can put everything back where they were ,so if anybody out there has done this and has a tip or two i would apprecite it.the dealer wants 200.00 to do this.i think it's a ripoff!!
