Ok... so finally got round to doing the front diff to match the gearing of the rear. I had removed the front driveshaft while I ran in the rear just to be safe... Coming up to 500 miles on the rear and all good so far...
Now... the front. Dana 30. with 4.56 gearing to match the back. What is the break in procedure for the front? Same as the rear; 20 miles then let it cool down completely. repeat a couple times? Do I have it in 4-wheel drive the whole time?
Help appreciated!
