I PURCHASED A MONKEY GRIP POSI LIMITED SLIP DIFF. FOR MY 2000 SILVERADO 1500 4X4 AND AFTER 3000 MILES IT STARTED MAKING NOISES. I REMOVE THE COVER TO CHECK MY DIFFERENTIAL AND WHAT A MESS!!! THEY INSTALLED BRASS BUSHINGS IN THE SATELLITE GEARS AND THE BUSHING STARTED TO COME OFF THE GEARS AND GRIND IN MULTIPLE PLACES. I CALL NATIONAL DRIVETRAIN AND EXPLAIN THE PROBLEM AND "ERIC" TOLD ME TO SEND IT BACK TO GET A NEW ONE UNDER WARRANTY BUT I EXPLAIN TO HIM THAT WAS GOING TO TAKE TO LONG AND I WAS GOING TO HAVE THE BRASS BUSHINGS MADE LOCALLY AND HE AGREE TO REIMBURSE ME FOR THE PRICE OF THE BUSHINGS ,IT WAS A TOTAL OF $45.00 DLLS. IT'S BEEN OVER 3 WEEKS AND I HAVE NOT RECEIVED ANY MONEY. I KEEP SENDING EMAIL AND I GET THE TYPICAL ANSWER " WE WILL PUT A CHECK IN THE MAIL FOR YOU",. MY QUESTION IS? HOW LONG DOES IT TAKE TO MAKE AND MAIL A CHECK? BESIDES ALL OF THIS CHECK FIASCO.....WHO IN THE HELL THINKS BRASS BUSHING WILL LAST IN THE SPIDER GEARS??? I WILL NOT BUY ANYTHING FROM NATIONAL DRIVETRAIN ANYMORE,I DON'T TRUST THIS COMPANY ANYMORE. ENJOY MY $45.00 DLLS.

Great people to deal with! Fast shipping. I ordered online and forgot one part I needed that was under a dollar and didn't want to place a second order. I called and talked to one of the salespeople and he got the extra piece put in. Thanks for the great customer service.
