Left Hand Steering Knuckle Assembly for Ford New Holland 40 Series and Case JX Series Tractors

Description

When your front end starts feeling loose and your tractor wants to wander down the road instead of tracking straight, that worn steering knuckle assembly is usually the culprit. This is the pivot housing that lets your front wheels turn while carrying the weight of the tractor, and when it gets worn out, you’ll feel it every time you try to make precise turns or keep the machine between the fence rows.

What You’re Getting

• Complete left-hand knuckle assembly that eliminates dangerous steering play
• Heavy-duty construction built to handle the constant pivoting and weight loads
• Direct replacement for the original equipment – no modifications needed
• Precise machining ensures smooth steering operation and proper wheel alignment
• Built to work with your existing tie rod ends and steering components

Built for Real Farm Work

This knuckle fits a wide range of mid to heavy-duty tractors including Ford New Holland 40 series machines from the 5640 utility tractor up to the big 8340 row-crop models. It also works on Case JX series tractors and several Fiat models. Whether you’re running a loader tractor around the farmyard or pulling heavy implements across rolling fields, this assembly handles the job.

Made to Last

Farm work puts tremendous stress on steering components – between the constant turning, heavy loads, and rough terrain, cheap parts don’t survive long. This assembly is built with quality materials and proper heat treatment to handle years of hard use without developing the play and looseness that makes steering feel sloppy and unsafe.

Good to Know

This is typically a job for someone comfortable with front-end work, as it involves supporting the tractor properly and working with heavy components. You’ll need to disconnect the tie rod and remove the old assembly before installing the new one. If you’re replacing one side, it’s smart to check the other side too since they usually wear at similar rates. Always use proper torque specifications when reassembling to ensure safe operation.
