hello to all
i've got a new gearbox and rear on its way to me.i hear a lot of people change the rear diff as well.the gearbox im gettn is the same as i've on in my car.so should i change the rear diff.???

 

so long as the ratios are matched there's no need to unless your rear diff is playing up. That said if it's younger/lower milage change it or just keep it as a spare if you have the space.

 

yea i think they are the same.how would i find out if there are the same.my rear diff is fine.i got plenty of room to keep it
