Inner Tie Rod Tool for Steering Arms 28–45 mm Length 400 mm 1/2" Square and 27 mm Hex, Beta Tools

Key Facts — Beta Tools 1566N Inner Tie Rod Tool

• Brand: Beta Tools
• Model: 1566N
• Type: Tool for removing and installing steering arms
• Capacity: Ø 28–35 mm or Ø 35–45 mm (select when ordering)
• Length: 400 mm
• Drive: 1/2" square or 27 mm hexagon

The Beta Tools 1566N loosens and tightens the inner tie rod joint right at the steering rack, without removing the steering gear. The tool slides over the tie rod and grips the joint around its full circumference, putting full torque onto a joint that sits deep behind the boot and cannot be reached with an ordinary spanner.

Two sizes are offered in this listing: 1566N 35X400 for joints Ø 28–35 mm and 1566N 45X400 for Ø 35–45 mm. Both are 400 mm long, enough to reach past the tie rod on most cars and light commercial vehicles. Select the size when ordering, based on the joint diameter.

The tool is driven either with a ratchet or breaker bar on 1/2" square, or with a 27 mm ring spanner on the external hexagon. The hexagon earns its place where space around the rack is too tight for a straight-line bar.

Why mechanics choose the Beta Tools 1566N

Because a tie rod change otherwise turns into guesswork with a pipe wrench. A joint seized by years of road salt needs high torque, and a pipe wrench slips, marks the joint housing and gives no controlled tightening torque on reassembly. With the 1566N, torque passes through a fixed connection at 1/2" or 27 mm, so a torque wrench can be used when tightening the new joint.

Applications for the inner tie rod tool

The tool is used for replacing tie rods and inner joints, changing steering rack boots where the joint has to come off, and alignment work where the tie rod must be released from the rack. It belongs in the general workshop, the tyre and alignment shop, and with anyone servicing their own vehicles who would rather not book the car in for a single tie rod change.

Technical Specifications

Used by: Vehicle mechanics, wheel alignment technicians, tyre shop staff, van service technicians and home mechanics.

Common in: Car workshops, wheel alignment and tyre service, light commercial vehicle servicing, motorsport.

Frequently Asked Questions (FAQ)

Which size of the Beta Tools 1566N fits my tie rod?

That depends on the outer diameter of the inner joint where the tool grips. The 1566N 35X400 takes Ø 28–35 mm and the 1566N 45X400 takes Ø 35–45 mm. Measure the joint with a caliper before ordering. At exactly 35 mm both fit, but the smaller tool grips better at the lower end of its range. For a workshop handling both cars and vans, the two sizes together cover 28–45 mm.

What is needed to drive the Beta Tools 1566N inner tie rod tool?

Either a ratchet, breaker bar or torque wrench with 1/2" square drive, or a 27 mm ring spanner on the external hexagon. No drive tool is included. For loosening a corroded joint, a 1/2" breaker bar gives the best leverage; for installation, a 1/2" torque wrench tightens the joint to the vehicle manufacturer's specified torque.

What separates the Beta Tools 1566N from a tie rod kit with interchangeable adaptors?

A fixed grip instead of an adaptor chain. A kit covers many diameters but passes torque through several connections, each with its own play. The 1566N is one solid tool per size range, 400 mm long, with 1/2" or 27 mm drive built into the body. That gives a steadier grip at high breakaway torque, at the cost of needing two tools to cover 28–45 mm.
