2021 Ram ProMaster Wheel Alignment Specifications

Quick reference

Adjustability

The 2021 Ram ProMaster has limited factory alignment adjustability. On the front axle, only individual toe is adjustable. This is done by loosening the jam nuts on the outer tie rod ends and rotating the inner tie rod to lengthen or shorten the assembly.

Front camber and caster are not adjustable from the factory. The front struts bolt to the steering knuckles in a fixed position. If the camber or caster angles are out of the specified range, it typically indicates that a component is bent or damaged, or that the vehicle's ride height has been altered.

The rear axle is a solid, non-adjustable beam. As such, there are no provisions for adjusting rear camber, toe, or caster. If rear alignment angles are out of specification, it points to a bent axle housing or damaged mounting points, which would necessitate parts replacement.

Recommended adjustment hardware

To correct front camber or caster angles on a 2021 Ram ProMaster, aftermarket parts are required. The most common solution is the installation of offset strut mounts or eccentric cam bolts. Reputable brands like SPC (Specialty Products Company) and Moog offer kits specifically for the ProMaster chassis. These kits create a method for repositioning the top or bottom of the strut relative to the vehicle body or knuckle, allowing a technician to dial in the camber and caster angles. For most ProMaster vans that have not sustained collision damage, a simple toe adjustment is all that is required.

Symptoms of bad alignment

A vehicle with improper wheel alignment can exhibit several noticeable symptoms, with tire wear being the most definitive sign.

• Vehicle pulling or drifting: The most common symptom is the vehicle consistently pulling to the left or right when you are trying to steer straight. This is often caused by unequal caster or camber from side to side.
• Crooked steering wheel: The steering wheel is not centered when driving straight. To keep the vehicle moving forward, you have to hold the wheel at an angle.
• Tire squealing: Particularly in turns, tires may squeal because they are not tracking properly.
• Uneven tire wear: This is the clearest indicator.
  • Camber wear: If camber is off, you will see excessive wear on one edge of the tire. Too much negative camber wears the inside edge, while too much positive camber wears the outside edge.
  • Toe wear: Incorrect toe will cause a "feathered" or "scalloped" wear pattern across the tire's tread. You can feel this by running your hand across the tread blocks; they will feel sharp in one direction and smooth in the other.

When to align

A wheel alignment is a critical maintenance task that should not be overlooked. It is recommended to have your ProMaster's alignment checked and adjusted in the following situations:

• After installing new tires: To ensure you get the maximum life out of your new investment and prevent premature wear.
• After replacing suspension or steering components: Any time a part that affects wheel geometry is replaced (e.g., struts, ball joints, control arms, tie rods), an alignment is necessary.
• After a significant impact: If you hit a large pothole, a curb, or are involved in a minor collision, the impact can easily knock your alignment out of specification.
• When you notice symptoms: If you observe any of the symptoms listed above, such as pulling or uneven tire wear, it is time for an alignment check.

Typical alignment cost

The cost of a wheel alignment for a 2021 Ram ProMaster can vary depending on your location, the type of shop, and whether additional parts or labor are needed to make adjustments. For a standard front-end alignment (which is all that is typically adjustable on this vehicle), you can expect to pay between $100 and $200. If aftermarket kits need to be installed to correct camber or caster, the cost will be higher due to the extra parts and labor involved.
