Frequently Asked Questions
Why do the steering box mounts on the 80 Series crack?
The 80 Series steering box is mounted directly to a relatively thin section of the chassis rail. Over time, heavy-duty off-roading, larger tyres, and the natural rotational force of the steering box create fatigue in the metal. Eventually, this leads to stress fractures, chassis flexing, or even complete failure of the mounting holes.
What are the signs that I need these repair plates?
Common signs include "loose" or vague steering, a knocking sound when turning the steering wheel, or visual cracks around the steering box mounting bolts. If you see the chassis rail moving or flexing when someone else turns the steering wheel while the vehicle is stationary, you likely have mounting fatigue that requires urgent repair.
Do these plates require welding for installation?
Yes, these repair plates are designed to be welded onto the chassis rail to provide structural reinforcement. By welding the plates into place, you effectively sandwich and bridge the damaged area, creating a much stronger mounting surface than the original factory chassis alone.
Should I install these even if my chassis isn't cracked yet?
Absolutely. These plates are an excellent "preventative" upgrade for any 80 Series that sees frequent off-road use, especially if you have fitted larger tyres or a steering damper upgrade. Preemptively strengthening this area saves you from expensive chassis repairs and the risk of losing steering control on the trail.
Can I install these myself at home?
If you are an experienced welder, yes. However, because this is a critical structural and safety component, we highly recommend having these plates professionally welded and inspected. Ensuring full penetration of the weld and correct alignment with the steering box mounting holes is vital for vehicle safety.
