You've received some very good advice here and Jeepwalker pretty much spelled it out correctly.I just found out i need a new rear axle assembly for my 2009 1500. Should i buy it new, used, or rebuild my existing one?

2wd or 4wd? Do you know gear ratio? If it is 3.55 as many of those 2009's, with your particular transmission the 545rfe, it is a perfect time to move to 3.92. If it is 4wd, you have to do both axles with new gears. That year had a tsb/recall on the gears, I'm not sure if the dealer would be held liable at this point or not. It is worth a try to go at them over this, try and guilt them into a fix or partial payment, but if it were me I'd move to 3.92' gears. It is better for the 545 rfe specifically. If you had a 65rfe, my recommendation might be different, but our 545rfe's have a lot of low rpm issues that can effect gears, transmission and engine. Moving to 3.92's fix a lot of this. If you have to pay for new gears anyway, why not upgrade?I just found out i need a new rear axle assembly for my 2009 1500. Should i buy it new, used, or rebuild my existing one?

I believe the TSB you are referring to was for a loose pinion nut? If the vehicle did not receive the retrofit, I would think the OP might have a claim.2wd or 4wd? Do you know gear ratio?
