Yes its time for me to buy the guts for both front and rear axles. I have bought a lot of this stuff throughout my addiction. But I can honestly say I don't have a favorite go to for this. I have had decent luck at the bronco vendors because they generally in tune with what I am looking for. I use Summit a lot for motor and trans parts plus bearings and seals when I have the numbers. Transfer case stuff I use a bronco vender. Drive shafts my favorite is Carolina driveline.. But differential parts I must say I dont have a favorite. Can you all send me in a good direction for this? I would like to have a favorite differential / parts vender.
Like everything else, it depends on what is important to you.
I will only buy genuine Spicer gears for the Dana axles. But set up time and noise are important to me. (not a fan of the SVL products.)
I am also the king of the budget build. So I harvest good used parts to save cost. If cost is important to you, (and obviously it is NOT, based on your sig line...) then buying used is the way to go.
If convenience is important, then Summit / Jegs will work.
For application support, Randy's R&P is good.
If you make a lot of mistakes, pick someone that has a liberal return policy.
For the most complete hardware solution, you cannot beat the MOPAR parts counter at the dealership.
If you have lots of time to waste, there are good deals on Ebay.
If you do all of the work to look up bearing and seal part numbers, then Amazon is your friend.
No one in their right mind buys individual components for axle parts. Kits are the way to go. Some kits are great, some kits suck.
If you are missing parts, No one has the right shims, baffles, and slingers except the OEM.
How many are you going to build? Are you going to do the work yourself, or do you have a builder? So many questions...
