Difference between OEM axles and EMPI or SOLID SHAFT axle, which can end up taking the life of your A4/A6/C5 Allroads and Avant.
Ive had 2 Allroads, one had EMPI and my current AR has OEM Axles from Raxles. First AR passed away when the Driver's side EMPI Axle broke from the inner point, pressuring my Engine and transmission from their mounts and tearing my Transmission for the underside of the car. Audi Volkswagen Specialist in Berkeley spent a month assessing the situation until my insurance took my AR and paid me out for my car.
Now I have gone the serious distance of ordering the pair of Raxles Axles for my Allroad. Raxles set comes with all the necessary tools needed to change the axles as well as a pre-paid label for you to send your cores back to Raxles. Located in Florida, it does take a long while to receive your package if you stay in Oakland California, but so normal OEM Rebuilt axles, go with Raxles.
EMPI axles are made from replicated OEM parts which do fit inline with the all of the hardware of your A6 or Allroad. However, the main shaft connected from the inner CV axle to the outer CV axle is made up of one piece of metallic rod, whereas the OEM axle is a hollowed out pipe that connects from the inner to the outer axle.
OEM Axles which Raxles makes consist of OEM inner and out rebuilt CV joints along with the original hollowed shaft in the middle. This shaft is a pipe that is circular at all points. Because it is circular, the shape of which has been formed has no weak spots at any point of the shaft, such as center weight that can unbalance the shaft, leading to a smooth ride with no unbalanced weight being thrown around from the axle.
Now, it might seem that there is much difference between a metal rod and a solid pipe, but there is. a Metal rod is not fully centered and balanced when measured at a degree of 0.0. So when you spin the axle at a low speed, Like a bucket of water being spun in a circle, water wants to move in the direction of the force applied, the mass of the center of the Rod will make the shaft revolve unequally thus causing the vibration in your steering wheel, chatter from the drive-train and if not take care of immediately, pressure being exerted to the rest of the drive-train components. All this because the shaft is unbalanced and not Trued, a centered revolution, and is rotation at high speed.
I ordered the pair my pair and this what I got for the prices. I hope you get your axles from RAXLES
Front - $216.00
Passenger - $216.00
Pair - $532.00
Shipping - $85.00 for 5-7 day shipping
$132.0 for 3-5 day shipping
Raxles also sends a pre-paid postage for your Cores as well, so when done, Pack up your old ones and send them back.
Also, the prices are pretty high and it might seem unreasonable. However, the C5 Allroad is a Rare wagon that needs great attention and with Raxles Limited Lifetime Warranty of a pair of axles that will last 10 years......... I wouldn't want to spend $120 for a Duralast or EMPI axle and sign the terminal certificate of death for my Allroad.
