Jeep Wrangler JK Axle Torque Specs: Hub, Track Bar and Arms
Jeep Wrangler JK Axle Torque Specs: Hub, Track Bar and Arms with application chart, generation boundaries, verification steps and official manufacturer lookup.
For the covered JK front hub, tighten the three hub-to-knuckle bolts to 75 lb-ft (102 N·m) and the front axle nut to 100 lb-ft (136 N·m). The cited suspension procedure uses 148 lb-ft for axle-side track-bar bolts with vehicle weight on the suspension.
For the covered JK front hub, tighten the three hub-to-knuckle bolts to 75 lb-ft (102 N·m) and the front axle nut to 100 lb-ft (136 N·m). The cited suspension procedure uses 148 lb-ft for axle-side track-bar bolts with vehicle weight on the suspension.
The hub values are anchored to a 2009 4WD Wrangler 3.8L and the suspension rows to a 2010 JK recall procedure. They do not describe every YJ, TJ, later 3.6L JK, JL, Dana axle or internal differential fastener.
Rubber-bushed control-arm and track-bar fasteners in the cited procedure are tightened with full vehicle weight on the suspension. Pinion nuts and differential bearing caps are intentionally excluded: pinion tightening establishes bearing preload and requires measured rotating torque, while caps must remain paired and oriented.

Jeep Wrangler Axle Torque Specs
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Front hub-to-knuckle bolts | 75 lb-ft | 102 N·m; three bolts |
| Front axle shaft nut | 100 lb-ft | 136 N·m; covered 2009 JK |
| Front/rear track bar to axle | 148 lb-ft | 200 N·m; suspension loaded |
| Front lower arm to axle | 140 lb-ft | 189 N·m; covered procedure |
| Rear upper arm to axle | 150 lb-ft | 203 N·m; covered procedure |
| Pinion nut | Preload procedure only | Never substitute a generic final torque |
Rubber-bushed control-arm and track-bar fasteners in the cited procedure are tightened with full vehicle weight on the suspension. Pinion nuts and differential bearing caps are intentionally excluded: pinion tightening establishes bearing preload and requires measured rotating torque, while caps must remain paired and oriented.
Hub hardware versus suspension hardware
The hub-to-knuckle bolts clamp the unit bearing and the axle nut secures the shaft/hub relationship. Control-arm and track-bar bolts locate the axle under the chassis and have different loads and installation conditions.
Label removed fasteners and attach every value to a named position. A memorized 100 or 148 lb-ft number is unsafe when applied to the wrong component.
Load rubber bushings before final tightening
The cited recall procedure requires full vehicle weight on the suspension for the control-arm, track-bar, stabilizer and shock fasteners. Tightening bonded-rubber bushings at full droop can preload and shorten their life.
Internal differential work is outside this chart. Bearing-cap position and pinion preload are assembly measurements, not generic bolt-list jobs, and require the exact Dana axle procedure and measuring tools.
Application boundaries for 2009–2010 Wrangler JK
The hub values are anchored to a 2009 4WD Wrangler 3.8L and the suspension rows to a 2010 JK recall procedure. They do not describe every YJ, TJ, later 3.6L JK, JL, Dana axle or internal differential fastener.

Pinion nuts and differential bearing caps are intentionally excluded: pinion tightening establishes bearing preload and requires measured rotating torque, while caps must remain paired and oriented.
Jeep 2009–2010 Wrangler JK specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Procedures used with this specification
These steps are the same for every vehicle in this family, so they are documented once rather than repeated on each page. The values above remain specific to this Jeep 2009–2010 Wrangler JK.
Jeep Wrangler JK Axle Torque Specs: Hub, Track Bar and Arms FAQs
What is the 2009 JK front axle-nut torque?+
The covered 4WD 3.8L procedure specifies 100 lb-ft (136 N·m).
What are the three JK hub-to-knuckle bolts torqued to?+
The cited 2009 installation procedure specifies 75 lb-ft (102 N·m).
When are JK control-arm and track-bar bolts tightened?+
The cited suspension procedure requires full vehicle weight on the suspension.
Can the pinion nut be tightened to a generic chart value?+
No. Pinion tightening establishes bearing preload and requires the exact axle procedure and rotating-torque measurements.
