Camber Adjustable Bolt Cam 8981864040 / 8-98186404-0 For ISUZU D-MAX TFR TFS Holden Colorado (2003–2024) — M16×102 Lower Link Bolt, High-Strength Steel, OEM-Spec

The Camber Adjustable Bolt Cam with OEM references 8981864040 / 8-98186404-0 (dashed form 8-98186-404-0) is a verified replacement suspension alignment fastener for ISUZU D-MAX, TFR, TFS, and Holden Colorado pickups across a broad production span from 2003 through 2024. This is the lower link / lower control arm cam bolt — the adjustable eccentric bolt that allows precise camber and alignment adjustment on the front suspension, ensuring even tire wear, stable straight-line tracking, and correct steering geometry.

The bolt is cataloged under several functional descriptions across the supply chain — "BOLT; LWR LINK" (Lower Link Bolt), "Boulon de biellette inférieure", and "Bulong Tay Dưới" — all referring to the same adjustable cam bolt that secures the lower control arm to the chassis frame while providing the eccentric adjustment range needed for professional wheel alignment. It is manufactured from high-strength steel to resist stretching and breaking under the cyclic loads of suspension travel and road impacts. The thread size is M16 × 102 (M16 diameter, 102 mm length), as confirmed by Thai-market parts data.

This is the eccentric cam bolt used for suspension alignment adjustment. It is not a standard fixed hex bolt, not a control arm bushing, and not a complete control arm assembly. The eccentric cam profile provides the adjustment range for camber and caster settings during wheel alignment.

The bolt is confirmed for ISUZU D-MAX (2003–2024), TFR/TFS variants, Holden Colorado, and Qingling (Ruimai) applications. It is not a universal suspension bolt — other ISUZU chassis (N-Series trucks, FSR, etc.) use different lower link fasteners. Confirm the vehicle model and year before ordering.

This listing covers 1 piece (1 PCS). The lower control arm cam bolt is typically required in pairs (left and right) or in multiples per vehicle depending on the suspension design. Confirm the required quantity per vehicle against the workshop manual or original fastener count before ordering.

• OE Reference Group Verified: 8981864040, 8-98186404-0, 8-98186-404-0
• Thread Size Verified: M16 × 102 — confirmed by Thai-market parts data (โบลท์ยึดปีกนกล่าง M16X102).
• Material Verified: High-strength steel — confirmed by PartSouq technical description ("High-strength steel construction ensures it resists stretching or breaking").
• Vehicle Coverage Verified: ISUZU D-MAX (2003–2024) — confirmed by Thai, Vietnamese, and French supplier listings. TFR/TFS, Holden Colorado, Qingling (Ruimai) — confirmed by PartSouq compatible model list and Vietnamese supplier data.
• Adjustment Function Verified: Camber adjuster / axis — confirmed by Euro4x4parts listing the equivalent KIT8-98186-404-0 as a "Control arm / wishbone lower – cam adjuster/axis" for D-MAX 2 (2012–2017).
• Genuine OEM Status Verified: The spare part is a genuine ISUZU part — "exactly the same as the one mounted at the factory when the vehicle was new".
• Material / Certification Reference (Aftermarket): Feimenlmugol brand with CE, ISO9000, TS16949, EMARK, SASO certifications — confirmed by Vietnamese supplier data.
• Net Weight NOT Publicly Disclosed: Accessible supplier data does not publish the net weight for this exact bolt. Confirm net weight at inquiry for freight planning — do not assume a weight from adjacent suspension fasteners without supplier confirmation.

• Inability to achieve or maintain correct wheel alignment: A worn or seized cam bolt prevents the alignment technician from setting camber/caster to specification, or the setting slips after adjustment — a direct sign the bolt is stretched or the cam profile is worn.
• Uneven or accelerated front tire wear: Incorrect camber from a failed cam bolt causes shoulder wear, cupping, or feathered edges on the front tires.
• Clunking or knocking from the front suspension: A loose or stretched lower link bolt allows the control arm to shift under load, producing a metallic clunk over bumps or during braking.
• Vehicle pulls to one side / vague steering: A cam bolt that has slipped from its set position changes suspension geometry, causing the vehicle to drift or require constant correction.
• Visible bolt stretch, thread damage, or corrosion: A stretched bolt (reduced cross-section at the threads) or severely corroded bolt compromises clamping force and cannot be safely reused.
• Cam washer / eccentric profile damage: A worn or damaged eccentric cam surface prevents the bolt from holding its adjustment position, allowing alignment to drift.

• Function and position are the first checks: This is the adjustable cam bolt for the lower control arm. It is not a standard fixed bolt and not an upper control arm bolt. Confirm the required position and adjustment function against the original unit.
• Quantity per vehicle: The bolt is supplied as 1 piece. Depending on the suspension design and whether both sides are being serviced, multiple units may be required. Confirm the required quantity against the workshop manual or the original fastener count.
• Thread size and length: The confirmed size is M16 × 102. Verify the original bolt's thread and length before ordering — a different size will not secure the lower link correctly or provide the correct adjustment range.
• Genuine vs. aftermarket: This bolt is available as ISUZU Genuine (factory-original) and as aftermarket (Aimiky, Feimenlmugol brands with CE/ISO/TS16949 certification). Confirm the buyer's requirement for OEM authenticity versus cost-effective aftermarket supply.

1. 1Confirm the required part first: Verify that the original bolt is the adjustable cam bolt for the lower control arm and that the replacement's thread size (M16), length (102 mm), and cam profile match the original unit.
2. 2Safety first: Park on level ground, engage the parking brake, and chock the rear wheels. Raise and support the front of the vehicle securely on jack stands.
3. 3Mark the alignment position: Before loosening the cam bolt, mark the cam washer position relative to the chassis bracket to preserve the existing alignment setting as a reference.
4. 4Remove the old bolt: Hold the cam washer or eccentric head to prevent rotation, and remove the nut. Note the orientation of the cam washer and any spacers.
5. 5Inspect the lower link and chassis bracket: Check the bolt holes for elongation, cracking, or corrosion. A damaged bracket or link requires replacement before installing a new bolt.
6. 6Install the new cam bolt: Insert the 8981864040 bolt through the lower link and chassis bracket. Seat the cam washer in the adjustment slot and install the nut.
7. 7Set the preliminary alignment: Adjust the cam position to approximate the original alignment setting (using the marks made in step 3) and snug the nut.
8. 8Torque the nut: Tighten the nut to the workshop manual specification. Do not exceed the specified torque — over-tightening can stretch the bolt or damage the cam profile.
9. 9Professional wheel alignment: Mandatory after installation. Adjust the cam bolt to achieve the specified camber/caster settings and verify toe alignment.
10. 10Road test: Drive the vehicle at low speed and check for abnormal noise, steering pull, or vibration before returning the vehicle to service.

• Inspect suspension fasteners at every major service or every 20,000–30,000 km — check for loose bolts, corrosion, and visible thread damage.
• Check wheel alignment after any suspension impact (curb strike, pothole) or if uneven tire wear develops — a slipped cam bolt may not be visually obvious.
• Replace the cam bolt whenever the suspension is disassembled for control arm or bushing service — used cam bolts may be stretched or have damaged threads and should not be reused.
• Use a calibrated torque wrench when tightening the cam nut — incorrect torque is a leading cause of alignment slip and bolt failure.

• Standard packing: Neutral packaging / wooden case / carton / plastic bag + wooden case + pallet — confirmed by supplier terms.
• Package contents: 1 × Camber Adjustable Bolt Cam. The matching nut and washer may or may not be included depending on the supply channel — confirm exact package contents at inquiry.
• Set options: Single bolt (standard) / bolt + nut + washer kit (where available) — specify at inquiry.
• Suitable for: ISUZU D-MAX / TFR / TFS / Holden Colorado suspension repair shops, pickup fleet maintenance departments, wheel alignment specialists, spare parts distributors, and export wholesalers.
