Why This Comes First
The OBS steering system uses a recirculating ball steering box connected to the front wheels through a series of joints and linkages — the idler arm, pitman arm, centre link and tie rod ends. On a 30-year-old truck that has lived in the UAE, every single one of those joints has wear in it. And wear is cumulative: a little slop in the idler arm plus a little slop in the pitman arm plus worn tie rod ends equals a truck that feels like it's steering through a bowl of porridge.
This is always the first job in any steering upgrade because until these wear items are replaced, you cannot accurately diagnose whether the steering box itself is the problem. Many owners buy a new steering box when what they actually needed was a front end rebuild. Do this first, feel the difference, then decide if the box needs attention.
Important: After this job, the vehicle must be 4-wheel aligned. Budget for this — it is not optional. Alignment in Sharjah runs 150–300 AED. Without it, you will eat through your new tie rod ends and tyres prematurely.
Also important: this guide, and the kit below, cover 1993–1998 trucks specifically. The idler arm bracket is a genuinely different part on 1988–1992 trucks, not just a different price on the same part. If your truck is a 1988–1992 model, hold off, get in touch and we'll confirm the correct earlier-years parts before you order.
What You Actually Gain
What You Need
Mandatory — Replace All Together
- Heavy-Duty Idler Arm Moog K6447
- Idler Arm Bracket Moog K6722 (inspect — but comes off the frame anyway, most replace both together)
- Pitman Arm Moog K6335
- Centre Link (Drag Link) Moog DS1407
- Tie Rod End Set — Inner & Outer Moog ES2838RL (inner) / ES2836RL (outer)
Recommended While Front End is Apart
- Front Wheel Bearings (inspect) Timken SET45 or equivalent
- Steering Knuckle Seals Inspect — replace if weeping
- Front CV Boots (4WD) Inspect whilst accessible
These aren't bundled in the kit below. Worth knowing before you order the bearings, OBScure Parts stocks two confirmed variants for this platform, non-ABS for 1988–1994 and ABS-equipped for 1995–1999, check which your truck needs.
Moog parts are the quality benchmark for this job. Avoid unbranded parts on steering components, this is not the place to save 40 AED.

Get the whole kit delivered
After writing this guide I went back and re-sourced every part on this list myself, that's how the wrong numbers above got caught. So I built an OBS-UAE front end rebuild kit through OBScure Parts, the parts store I also run, sourcing everything mandatory as one order. It's priced lower than buying the parts individually, bundled shipping, handling and logistics makes that possible. Full story on why it exists here.

The Process
- Lift vehicle and support on stands. Remove front wheels both sides.
- Mark tie rod end positions on threads before removal — this preserves approximate alignment and saves time at the alignment shop.
- Remove outer tie rod ends using a ball joint separator. Do not hammer the tapered studs.
- Remove inner tie rod ends from centre link.
- Remove centre link from idler arm and pitman arm.
- Remove idler arm from frame bracket. Inspect bracket — replace if worn or cracked.
- Remove pitman arm from steering box using a pitman arm puller. Do not use a pickle fork — it will damage the seal.
- Install new pitman arm. Torque to 185 Nm.
- Install new idler arm and bracket. Torque bracket bolts to 95 Nm.
- Install new centre link. Connect to pitman arm and idler arm.
- Install new inner and outer tie rod ends. Thread to marked positions.
- Torque all tapered stud nuts. Install cotter pins.
- Refit wheels. Take immediately for 4-wheel alignment.
Hand This Over
"Replace the front end steering components: idler arm, idler arm bracket, pitman arm, centre link, and both inner and outer tie rod ends. Use Moog parts only, no unbranded parts on steering. Use a proper pitman arm puller, do not use a pickle fork on any tapered joints. Mark the tie rod positions before removal. After the job, the vehicle needs a 4-wheel alignment, do not return it without this."
This Upgrade Fits
Continue the Steering Upgrade Path
- Next — 1.2b Steering Box Upgrade — now that the front end is sorted, you can accurately feel what the box contributes. Many owners find the front end rebuild alone transforms the truck. Others go further.
- Next — 1.2c Borgeson Steering Shaft — eliminates the rag joint flex between the wheel and box. Independent job, can be done any time.
