A Subaru lower control arm bolt secures critical suspension components in their intended position. If a bolt is removed during control arm, bushing, or suspension work, the correct replacement hardware matters for proper installation and alignment. Subaru part number such as 901000110 is used as a lower control arm bolt in multiple Subaru applications and should be matched to your vehicle before ordering.

Small Hardware With an Important Suspension Job

Control arms help connect the wheel and steering knuckle to the vehicle while allowing the suspension to move through its normal range. The bolts holding those components together need to maintain the correct clamping force under braking, cornering, bumps, and everyday road loads.

A worn, damaged, corroded, stretched, or incorrectly sized control arm bolt should not be treated as ordinary hardware. This is especially important for Subaru owners who regularly drive through snow, road salt, rain, gravel, or on rough roads, where suspension components and fasteners are repeatedly exposed.

Why Genuine Subaru Hardware Matters

A bolt for lower control arm service must have the correct diameter, thread pitch, length, strength, and mounting application. A generic bolt that physically fits through the opening may not meet the same specifications required for the suspension joint.

Genuine Subaru hardware removes much of that guesswork. Part 901000110 is designed for specific Subaru suspension applications and is listed as non-reusable once removed. Following those replacement requirements helps maintain the intended joint clamping and suspension installation.

While a control arm bolt does not directly operate Subaru Symmetrical AWD, suspension geometry, tire contact, and wheel alignment all contribute to predictable handling. Keeping suspension hardware secure is particularly important during wet, snowy, or uneven-road driving.

How to Choose the Right Lower Control Arm Bolt

Start with your Subaru's year, model, trim, engine, and suspension configuration. The same vehicle can use different fasteners depending on the location of the control arm or production details.

If you are searching specifically for 901000110, verify that number against the parts diagram or your VIN before ordering. Also determine whether related nuts, washers, bushings, or control arms require replacement during the repair.

During installation, follow Subaru service procedures and specified torque values. Suspension fasteners should not be tightened based on guesswork, and parts identified as non-reusable should be replaced rather than reinstalled.

Frequently Asked Questions

What is Subaru part number 901000110?

901000110 is a genuine Subaru suspension bolt used in lower control arm and related mounting positions on multiple applications.

Can I reuse a Subaru lower control arm bolt?

Not always. Subaru specifically lists 901000110 as a part that cannot be reused or reinstalled, so it should be replaced when removed from an applicable repair.

Can I use a hardware-store bolt for a lower control arm?

That is not recommended. Suspension hardware needs the correct dimensions, thread specifications, strength, and application.

Should I replace the control arm bushing at the same time?

Inspect the bushing for cracking, separation, excessive movement, or deterioration. Replace it when wear is present or when required by the repair procedure.

Do I need an alignment after replacing control arm parts?

An alignment may be appropriate after control arm or suspension work because those components can affect wheel geometry. Check the repair procedure and alignment specifications for your Subaru.
