InMotion WLK001A Suspension Knuckle Assembly - Rear Left
Rear Left Steering Knuckle Assembly for Explorer and Mountaineer
The InMotion WLK001A is a rear left suspension knuckle assembly for select 2002-2005 Ford Explorer and Mercury Mountaineer models. It is built as a direct replacement assembly to simplify knuckle and wheel bearing service on the rear left side.
Key Features
- Part number: WLK001A
- Rear left suspension knuckle assembly
- Pre-assembled replacement for the knuckle and wheel bearing service area
- Fits 2002-2005 Ford Explorer, rear left
- Fits 2002-2005 Mercury Mountaineer, rear left
Product Details
Traditional knuckle and wheel bearing replacement can require disassembly of multiple components and specialized tools such as a bearing press. The InMotion WLK001A provides a simpler service path by supplying the steering knuckle assembly as a ready-to-install unit. For technicians working on a Ford Explorer rear left knuckle replacement or a Mercury Mountaineer rear left wheel bearing service, this assembly reduces the need to transfer individual parts during the repair.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Repair
- Rear left knuckle damage from corrosion, impact, or wear
- Wheel bearing service that requires knuckle removal
- Time-consuming disassembly of individual suspension components
- Risk of damage during press-out or press-in procedures
- Repeat labor on 2002-2005 Ford Explorer and Mercury Mountaineer rear left applications
Installation Notes
Install on the rear left position only. Verify vehicle year, make, model, and side before ordering. Common hand tools are used for installation, and the original knuckle is removed before the replacement assembly is bolted in place.
Quality Assurance
InMotion supplies this steering knuckle assembly as a complete replacement unit for the listed applications, with components pre-installed on the assembly as described by the manufacturer.
