DropTopPony said:I asked 2 very reputable mechanics in my area..
1, he said take it easy for 500 miles and you will be set forever
2, he said the end of the driveway...then your broke in
I tend to be cautious i took it easy for a few hundred miles.
St33da said:As a mechanic my self, I would say that once they are in, there is no break in period. Once the shims are set and your pinion depth is proper, and your backlash patter looks good.... then thats it. If properly installed, then nothing should change between the 1st mile and the 100,000th. Now if you were rebuilding a differential with new clutches in it.... thats a different story all together. Then I would suggest 500 miles or so to break them in properly.

Better to be safe then sorry, and besides taking it easy on her for a few hundred with gas prices the way they are cant be too bad haha.
