Description
Product Overview
The DOFOCH Rear Differential Bearing Repair Kit is a comprehensive solution designed specifically for Cadillac ATS (V4/V6 2013‑2019) and CTS (V4/V6 2014‑2019) models. Engineered to meet or exceed original equipment specifications, the kit includes a large double pinion bearing, a small double pinion bearing, two tapered roller bearings, two rear axle shaft seals, a differential oil seal, and a dedicated disassembly tool. Constructed from high‑strength steel with precision‑ground surfaces, each component delivers optimal load distribution and reduced friction. The kit’s dimensions (16 x 10 x 5 inches) and weight (7.05 lb) make it easy to handle during installation, while the inclusion of OE/OEM part numbers (F‑577158, F‑574658, Lm50134R, 22993016, 92230584) guarantees exact compatibility.
Usage
Designed for both professional workshops and skilled DIY owners, this kit is ideal for routine maintenance, wear‑related replacements, or performance upgrades. Install the bearings when you notice differential noise, gear whine, or oil leakage. The kit’s seals effectively block contaminants such as mud, water, and dust, preserving lubricant integrity in harsh driving conditions. Suitable for daily commuting, long‑distance travel, and spirited driving, the kit ensures the rear differential operates smoothly across a wide temperature range.

FAQ
Is this kit compatible with turbocharged Cadillac models?
No. The kit is not designed for ATS V, CTS V, or Twin Turbo variants. It is intended for naturally aspirated V4/V6 engines within the specified years.
Do I need additional tools to install the kit?
The kit includes a purpose‑built disassembly tool that handles most removal tasks. Standard hand tools such as wrenches and sockets are sufficient for the remaining steps.
Can I use this kit on other vehicle brands?
The bearings and seals are engineered specifically for the listed Cadillac models. While some components may physically fit similar differentials, using the kit on other brands could lead to improper clearances and premature wear.
What is the recommended torque specification for the bearing caps?
Refer to the Cadillac service manual for exact torque values, typically ranging between 30‑45 Nm (22‑33 lb‑ft) for rear differential bearing caps.
How long does installation usually take?
For an experienced technician, the complete replacement can be performed in 1.5‑2 hours, including fluid drain and refill.
