THIS LIMITED WARRANTY issued by A Used Parts, LLC. warranties that used axle assemblies, carriers, and differentials are warranted to be free of any internal defects in material or workmanship. Repair or replacement of a defective axle assembly, carrier, and differential will be provided under normal use and proper maintenance set forth by the manufacturer, subject to the following terms and conditions.
Definition of a used axle assembly, carrier, or differential:
The above mentioned part names and others are often used to describe the same type part. For example a person may refer to a rear end assembly as a differential or axle assembly. AUP does not sell gear sets unless specifically noted, only assembled units with housing. These parts are sold as a replacement used part for the vehicle listed on this agreement. These parts are sold by application and condition only and not year, make or model. AUP does not include any brake parts on an axle assembly, carrier or differential unless listed on your invoice. We consider the brake parts (caliper, rotor, hub, drum, brake cables) as an add-on part. If any of these parts are included on the part you ordered but not listed on the invoice, they are considered as complimentary and can be used at the installer discretion. AUP always recommends new pads or shoes. Add-on parts are specifically excluded from any warranty offered herein.
Single wheel application:
(a) Standard Warranty: 36 months unlimited miles.
(b) Non-transferable Warranty: Valid only to the original owner, warranty terminates upon sale or transfer of vehicle.
Dual wheel application or Commercial use:
(a) Standard Warranty: 12 months unlimited miles.
(b) Non-transferable Warranty: Valid only to the original owner, warranty terminates upon sale or transfer of vehicle.
Covered Components:
Axles mounted inside the housing, internal gears, and bearings.
Repair or Replacement:
AUP at its sole discretion, has the option to repair the purchased used part or replace it with a similar product. In case of a mechanical defect, the buyer must notify AUP for instructions and authorization prior to making any repairs or replacements. However, if any repair to the defective part exceeds 25% of the total purchase price, AUP at its discretion may ask the part to be made available for pick up to be returned for repair or replacement. Any part being returned for repair, replacement or refund must be returned as sold completely assembled with all add-on parts attached and be packaged or palletized in the same manner the part was when delivered. If a suitable replacement is not available AUP will refund the purchase price of the used part purchased.
Used parts unless otherwise stated are eligible for refund for the period of 90 days from date of purchase. Any request for a refund or reimbursement for an authorized repair may be made by phone, email, fax or in writing. The refund period can take up to 15 days after the used part is returned and signed for by AUP or its supplier. Good items returned are subject to a 20% restocking charge and shipping costs. After 90 days, the warranty covers replacement or repair only.
AUP shall, at its option repair, replace or refund the defective parts within the warranty term without charge to the buyer subject to the limitations listed herein:
The warranty is voided by the following:
(a) Misuse, negligence, alterations, accidents or fire.
(b) Improper installation or repair.
(c) Lack of lubrication, improper lubrication level, using lubrication not recommended by the manufacturer or not following the manufacturers recommended maintenance schedule.
(d) Damage to a covered component due to a non-covered component failure.
(e) Incidental and consequential damage.
(f) Claims occurring outside the United States.
(g) Any repair or replacement not authorized from AUP in writing or email.
(h) Dismantling the used parts without authorization from AUP in writing or email.
(i) Water, dirt sand or other contamination.
The following are at the expense and obligation of the buyer
(a) Do a visual inspection. Ensure the parts you receive match the parts you need. On assemblies, match up shock mounts, mounting pads, spring pads and backing plate to backing plate width as needed. If it is a carrier/differential check axle flanges, driveshaft flange and insert the drive axle to make sure the spline fits properly. Make sure your wheel fits the axle pattern. Inspect the housing to make sure it is not bent. If you ordered the correct part and AUP sent an incorrect or defective part, AUP will be responsible for round trip shipping cost as stated in your order confirmation and warranty. Reuse your brake calipers and or brake parts. If the calipers were included on your replacement differential it is for the convenience of the installer. AUP does not warranty any brake components.
(b) Replace brake pads or disc pads with new if possible. If not, ask the installer if the parts from your vehicle are reusable. It is very easy to service the brakes during installation and will save money instead of preforming the work later.
(c) Inspect hydraulic lines, hoses and brake cables. Some of these type lines carry the fluid that operate the brakes. Replace as needed, ask the installer if your lines/hoses or cables are reusable. Sometimes these parts are cut or damaged during removal from the donor vehicle.
(d) Check gaskets and seals. Some of the axle assemblies, carrier/differential assemblies have had the rear cover removed for inspection. Ask your installer is a replacement gasket for the rear cover is needed. AUP always recommends replacement to avoid any leaks. AUP does not warranty any gaskets and seals.
(e) Check fluid levels. Some units are drained before shipping. Always use dealer recommended fluid so you do not void the warranty. Operation this type part with no fluid, a low level of fluid or the wrong fluid will damage the unit.
(f) Use a gasket or 100% silicone to seal the cover or third member to the housing. Use only high quality name brand gear oil and fill the differential until the oil spills out the plug hole. We DO NOT recommend using synthetic oil with any clutch-type Limited-Slip/Posi Differentials. Clutch-type posi-traction carriers require conventional oil and friction modifier (additive) to function correctly.
(g) If equipped, inspect wheel lug studs. Check the threads by running a lug nut up and down the studs to remove debris and make sure the threads have not gotten damaged. If a stub is missing or not acceptable, remove a stud from your vehicles axle and reinstall on the replacement unit. AUP does not cover the wheel lug studs.
Limited Liability
(a) AUP liability under this warranty is solely limited to the repair or replacement of a defective used Axle Assembly, Carrier, Differential, or Rear End Assembly. The labor required to repair a used Axle Assembly, Carrier, Differential, or Rear End Assembly and or remove it from a vehicle, and any other expenses relating to turn-over and other incidental charges for a defective part are not reimbursable.
(b) AUP shall not be liable for consequential, incidental, or special damages, or for any sold by AUP.
Limited Warranty
This warranty is in lieu of all other express warranties of AUP. Any implied warranty is limited in duration of this written warranty. AUP does not assume or authorize any distributor, dealer, agent or employees to enlarge, alter or extend the warranty, or to assume any other obligations on its behalf. This warranty does not apply to performance use or used for competition.
