YUP If they send another assembly I will have the guy working on the boy's jeep inspect everything before buttoning it up!

 

Well, after sending back a very specific email that answered the questions posed to me as well as providing them additional information, they are sending me a new assembly.

They did ask me to verify that no one had switched out the gears for a 3:73 and that it was still a 3:55. We had not actually checked that when we got it as I had asked them prior to shipment what the gear ratio was and they told me it was a 3:55.

Needless to say, I will have the guys at the towing place check the gears. I know the requirement was for a 3:55 as we verified the gearing of the old differential before I bought the replacement. Not sure why they want me to verify this but I have no problem doing this.

 

lol, good to hear.

 

What axle are you putting in this thing? Is it lifted? Dana 44?

Why would you purchase an axle assembly with 3.55 gears?!

 

This is a pure stock vehicle that my son bought. Dana 30 setup with standard 3:55 gearing. My understanding is the 3:73 gearing was put in vehicles with a tow package which this does not have. I have the guy at the towing place verifying the rear differential ratio as well in the off chance that the rear is actually a 3:73 instead of a 3:55.

My son verified that the original front diff was a 3:55 so the assumption was that the rear was 3:55 as well. May have been a bad assumption but given the fact that the vehicle was running with the 3:55 front before he bought it and made it up to DC with no problems from Norfolk after he bought it, it was a pretty solid bet that the assumption was a fact. Regardless, I am making absolutely sure that things are straight before the repairs are done.
