Dodge D150 Suspension Control Arm Bushing Replacement Guide (1977-1993)
Restore your truck's steering and ride quality by replacing worn control arm bushings.
- Clunking noises and steering wander are the most common symptoms of bad control arm bushings on a D150.
- Choose between a quiet, comfortable ride (rubber) and improved durability and handling (polyurethane).
- A ball joint press or bushing press is required for DIY replacement; these can often be rented.
- A wheel alignment is essential after replacing control arm bushings to prevent tire damage.
Is Your D150's Front End Making Noise?
If you're hearing clunks, feeling vibrations, or fighting with the steering wheel, your control arm bushings may be worn out. On a 1977-1993 Dodge D150, these bushings are made of rubber that degrades over decades of use. When they fail, the metal control arm can move around too much, causing a range of problems. Replacing them can make your classic truck feel tight and responsive again.
Symptoms of Bad Control Arm Bushings on a Dodge D150
- Clunking or Popping Noises: The most common sign is a metallic clunking sound from the front suspension, especially when going over bumps, braking, or making sharp turns. This is the sound of loose metal parts hitting each other.
- Steering Wander: Your truck may pull to the left or right on its own, forcing you to constantly correct the steering wheel to drive straight.
- Uneven Tire Wear: Worn bushings throw off the wheel alignment, causing the inside or outside edges of your front tires to wear down much faster than the rest of the tread.
- Vibrations: You might feel vibrations through the steering wheel or the floor, particularly at higher speeds. This happens because the worn bushings can no longer absorb road harshness effectively.
Don't Ignore the Signs
While you can still drive with worn bushings, it's not recommended for long. Severely worn bushings can affect steering control and lead to premature wear on your tires and other suspension components like ball joints.
Choosing the Right Aftermarket Bushings
For a vehicle from this era, new OEM parts are generally not an option. The aftermarket offers several excellent choices that often meet or exceed original quality. Your choice will depend on your budget and how you use your truck.
Material: Rubber vs. Polyurethane
- Rubber Bushings: These will give you a ride that's most like the original. Rubber is excellent at absorbing vibrations, resulting in a quieter, more comfortable ride for daily driving. However, rubber can wear out faster than polyurethane.
- Polyurethane Bushings: Often called "poly," this is a popular upgrade. Polyurethane is much more durable than rubber and provides a firmer, more responsive feel. This can improve handling, which is great for a work truck or performance use. The trade-off is a potential increase in road noise and vibration. Poly bushings may also need to be lubricated during installation to prevent squeaking.
Brand Tiers for Your D150
| Brand Tier | Brands | Typical Price Per Kit (Upper or Lower) | Best For |
|---|---|---|---|
| Premium / Heavy-Duty | Moog | $40 - $60 | Owners who want maximum durability and performance, often considered a "problem solver" brand with quality that meets or exceeds OE specs. |
| Mid-Grade | Mevotech | $30 - $50 | A good balance of quality and price, offering reliable performance for daily driving and light-duty use. |
| Economy | Dorman | $20 - $40 | A budget-friendly option for getting your truck back on the road safely. A practical choice for standard daily driving. |
Pro Tip: Replace in Pairs
It's best practice to replace both the driver and passenger side bushings at the same time. If one side is worn out, the other is likely not far behind. Also, consider replacing both upper and lower bushings for a complete front-end refresh.
Frequently Asked Questions (FAQ)
Do I have to replace the whole control arm?
No, you can replace just the bushings. This is more labor-intensive because the old bushings must be pressed out of the arm and new ones pressed in. However, it is much cheaper than replacing the entire control arm assembly. You should inspect your ball joints and the control arm itself for damage or rust before deciding.
Do I need an alignment after replacing the bushings?
Yes, a front-end alignment is highly recommended after this job. Replacing the bushings will change your current alignment settings, and a proper alignment is necessary to prevent uneven tire wear and ensure your truck drives straight.
Is this a difficult job to do at home?
This is a moderately difficult job. It requires safely lifting and supporting the truck, removing the control arms, and using a special tool like a ball joint press or bushing press to swap the bushings. These tools can often be rented from auto parts stores. If you are not comfortable with heavy suspension work, it's best to leave this to a professional mechanic.
How do I know if I have the 3000lb or 4000lb front end?
Some D150 models, especially those with heavy-duty packages, came with different axle weight ratings. While this primarily affects the ball joints, it's wise to check your truck's specifications before ordering parts. The VIN or a tag on the driver's side door jamb often contains this information. When in doubt, check with the parts supplier.
