Hummer H2 Alignment Camber Caster Cams

Hummer H2 Alignment camber caster cams

Starting at $9.95, AutoBuffy stocks 2 alignment camber caster cam bolts from ACDelco and MOOG. A camber caster cam bolt is an eccentric fastener that sits in the control arm or strut mount and rotates to shift wheel angle, letting technicians dial in camber and caster settings. When it seizes, strips, or slips, alignment cannot be held and tire wear accelerates rapidly.

Signs your Hummer H2 needs a new alignment camber caster cam

  • Uneven or rapid tire wear on the inner or outer edge that returns shortly after a fresh alignment
  • The vehicle pulls consistently to one side even after an alignment has been performed and verified
  • A technician reports that camber or caster is out of spec and cannot be brought within range during alignment
  • Visible corrosion, cracking, or a seized cam bolt that will not rotate when the alignment rack operator attempts adjustment
  • Clunking or popping from the front suspension when turning or going over bumps, caused by a loose or worn cam bolt shifting under load
  • Steering wheel sits off-center on a straight road, indicating caster imbalance that the existing cam can no longer correct

Which alignment camber caster cam should you buy for your Hummer H2?

The main decision is whether to replace only the cam bolt and nut or to buy a complete kit with the sleeve, hardware, and any required washers. You should also consider the adjustment range of the cam — stock-replacement cams restore factory range, while extended-range aftermarket cams allow correction on lifted or lowered vehicles where geometry has shifted beyond OE limits.

OE-Equivalent Cam Bolt & Nut
Best for
Stock-height vehicles needing a direct replacement after corrosion or damage
What you get
Factory adjustment range, correct fitment, single-use hardware that meets OEM spec
Complete Cam Kit (bolt, nut, sleeve, washers)
Best for
Any replacement job where surrounding hardware is also corroded or worn
What you get
All fasteners needed in one box, eliminates multiple trips, ensures mating surfaces are fresh
Extended-Range Aftermarket Cam
Best for
Lifted or lowered Hummer H2 where stock cam range cannot bring alignment into spec
What you get
Greater eccentric offset for more camber/caster correction, often billet construction for durability
Slotted Cam Bolt Set (pair)
Best for
Track or performance use requiring repeatable, precise corner-by-corner adjustment
What you get
Two matched cams for consistent left-right adjustment, typically with locking hardware to prevent slippage under load

Replacing alignment camber caster cams on a Hummer H2

Raise and support the vehicle, then remove the wheel to access the cam bolt location on the strut mount or lower control arm. Apply penetrating oil generously if the bolt is corroded, mark the original cam position for reference, then remove the nut, rotate the cam bolt out, and install the new cam in its place. Snug the nut to specification and then take the vehicle directly to an alignment shop, as the final cam position must be set on a rack — do not fully torque the nut until the alignment tech has dialed in the correct angle.

Frequently asked questions

How much does it cost to replace alignment camber caster cams on a Hummer H2?
Parts start at $9.95 on AutoBuffy. A full repair — including new cam bolts, hardware, and a post-installation wheel alignment — typically runs more when labor is added. Buying quality cams upfront and having the alignment set immediately after installation avoids a repeat visit and protects your tires.
Can I drive my Hummer H2 with a seized or broken camber caster cam?
You can drive short distances, but it is not advisable. A seized cam locks the wheel at whatever angle it is stuck at, meaning camber or caster will be out of spec. This causes accelerated tire wear, a pulling sensation, and reduced straight-line stability. Replace the cam and realign as soon as possible.
Do I need an alignment after replacing camber caster cams on a Hummer H2?
Yes, always. Installing a new cam bolt disturbs the existing wheel angle setting. Even if you mark the old bolt's position before removal, the new cam must be set precisely on an alignment rack. Skipping the alignment after replacement defeats the purpose and risks uneven tire wear returning immediately.
How do I know if my Hummer H2 needs a cam bolt or a different alignment part?
If an alignment technician says camber or caster is out of range and cannot be adjusted — not just out of spec — the cam bolt is likely seized, stripped, or at its limit. If the spec is adjustable but keeps drifting back, inspect for worn control arm bushings or a bent strut, which are separate issues.
Are camber caster cam bolts sold individually or in pairs?
Both options exist. Single cam bolts let you replace only the damaged side, which is fine if the other is in good condition. Pairs are common for front axle replacements where both sides have similar mileage and corrosion exposure. Check the specific listing to confirm quantity before ordering for your Hummer H2.
Will an extended-range cam bolt fit my stock Hummer H2 without other modifications?
Generally yes — extended-range cam bolts are designed to fit the same mounting holes as OE bolts. However, the additional offset they provide is only needed if your vehicle is lifted, lowered, or has alignment angles that fall outside the factory adjustment window. On a stock Hummer H2 they work fine but offer adjustment range you may never use.
