I have a 2013 Sahara unlimited with the dana 44 trak loc rear axle. Are the diff cover bolts supposed to be SAE or Metric? I bought this vehicle used last year and the track loc was worn. The dealer I bought it from replaced the clutch pack last year under warranty. I was just under there today and I took a look at the bolts and the bolts are 8.8 metric except one which is grade 5 sae. When I look up the bolts on mopar sites it looks like they are supposed to be 5/16 sae. If they are supposed to be sae I am not sure if the dealer swapped them. The dealer is one of those used car chains.
