- A failing steering rack is a critical safety issue; address symptoms like leaks or stiff steering immediately.
- The 2007 Isuzu i-290 shares its steering rack with the 2004-2008 Chevy Colorado/GMC Canyon, which can help in sourcing parts.
- A new aftermarket steering rack offers a balance of quality and affordability compared to a more expensive OEM part.
- A professional wheel alignment is mandatory after replacing the steering rack to ensure safety and prevent tire damage.
Is Your i-290's Steering Rack Failing?
A failing steering rack is a serious safety issue that makes your truck difficult to control. Since the 2007 Isuzu i-290 is mechanically identical to the Chevrolet Colorado and GMC Canyon, it shares the same common steering rack problems. The most frequent issue is leaking power steering fluid from the internal seals. This leak can cause a loss of power assist, making the steering wheel very hard to turn.
Key Symptoms to Watch For:
- Power Steering Fluid Leaks: Puddles of red or brown fluid under the front of your truck are a clear sign. Leaks often come from the rubber boots at either end of the rack.
- Stiff or Heavy Steering: If turning the wheel suddenly requires a lot of effort, especially at low speeds, the rack may have lost hydraulic pressure.
- Grinding or Clunking Noises: A grinding sound when turning can mean metal-to-metal contact inside the rack due to lack of lubrication from a fluid leak.
- Loose Steering or "Wandering": If you have to constantly correct the steering wheel to keep the truck straight, the internal gears of the rack may be worn out.
Recalls & Technical Service Bulletins (TSBs)
As of early 2026, there are no specific recalls or TSBs from Isuzu or GM for steering rack failure on the 2007 Isuzu i-290. However, owners of the identical Chevrolet Colorado have reported steering rack failures. Always check for the latest recalls using your vehicle's VIN on the NHTSA website.
Choosing a New Aftermarket Steering Rack
When replacing the steering rack on your i-290, you have a choice between original equipment (OEM) and aftermarket parts. Since new OEM racks can be expensive and hard to find, a new aftermarket unit is often the most practical choice.
- OEM (Original Equipment Manufacturer): An OEM rack, likely from AC Delco (GM's parts brand), is identical to the one your truck was built with. It guarantees perfect fit and function but comes at the highest cost.
- New Aftermarket (e.g., "Replacement" Brand): Aftermarket brands like "Replacement" produce new parts designed to meet or exceed OEM specifications. They offer a direct fit and reliable performance at a much lower price point, making them a great value. These parts are manufactured in facilities that are often ISO 9002 certified, ensuring quality control.
Pro Tip: The 2007 Isuzu i-290 shares its steering rack with the 2004-2008 Chevrolet Colorado and GMC Canyon. This interchangeability gives you more options when searching for a part. Always confirm fitment using your vehicle's specifications, paying attention to details like 2WD vs 4WD and specific suspension packages (e.g., Z71, Z85).

Frequently Asked Questions
Do I need to get a wheel alignment after replacing the steering rack?
Yes, absolutely. Replacing the steering rack will change your truck's wheel alignment. You must have a professional four-wheel alignment performed immediately after the repair to ensure safe handling and prevent rapid tire wear.
What is a "core charge"?
Many remanufactured steering racks, and some new ones, have a core charge. This is a refundable deposit you pay when you buy the part. You get the deposit back when you return your old, failed steering rack to the seller.
Should I replace the outer tie rod ends at the same time?
It is highly recommended. The outer tie rod ends connect the steering rack to the wheels and must be removed during the replacement. Since you are already paying for the labor, replacing them at the same time is cost-effective and ensures the entire steering system is in good condition. Many new aftermarket racks come with new inner tie rods already attached.
Is it difficult to replace the i-290 steering rack myself?
This is a moderately difficult job for a DIY mechanic. It requires safely lifting and supporting the vehicle, using special tools like a tie rod end puller and flare nut wrenches for the hydraulic lines, and properly bleeding the power steering system afterward. If you are not experienced with major suspension or steering work, it is best to leave this job to a professional mechanic.
