Rear diff question issue problem
Alright first of all I have a fleet of 15 F450' and 550's I have 2 F 350's and 2 -250's. Now with that said I have in all my 38 years of being in business never had a single company vehicle have rear end failure, yet I have had two of my personal trucks have rear ends blow up on me. First was an 07 F350 SRW crew cab long bed with a 6.0. When I bought it from dealer I had them swap the gears to 4:56. 150,000 miles in and bam. Now this week on my E99 F250 I am 165,000 in and whack goes the gears. I have been running a synthetic gear oil in th 99.
I tow heavy prolly once every 2 or three months, the rest of the time it's just a wakeboard boat on the weekends. You think this is coincidence or am I possibly doing some driving habit I shouldn't?
