Signs it is due

- Front end that dives and stays down over bumps
- Ring of grime pushed above the dust seal

Tools you need
- Front paddock stand or headstock support
- Seal driver and a circlip pick
- Graduated cylinder for the oil air-gap
- Torque wrench and fresh fork oil to the specified weight
Torque figures for this job
General ranges for these fastener classes. Confirm the exact figure in the service manual for your model and year before final tightening.
| Fastener | Range | Note |
|---|---|---|
| Top yoke clamp bolts | 20–25 Nm | Set fork height first, then torque the top yoke last. |
| Bottom yoke clamp bolts | 20–27 Nm | Alternate between bolts in two passes so the leg is not pinched off-square. |
| Fork top cap | 20–30 Nm | Cracking it loose while the leg is still clamped in the yoke saves a fight. |
| Damper rod bolt in the fork bottom | 18–25 Nm | Needs thread-lock; it backs out under damping loads if left dry. |

How to replace fork seals
1. Support the front
Take the weight off the front wheel, then remove the caliper, wheel, mudguard and clamp bolts.
2. Drop the legs
Slide each fork leg out of the yokes, keeping the leg upright to hold the oil.
3. Strip and clean
Remove the dust seal, circlip and oil seal, then clean the stanchion and inspect for pitting.
4. Fit new seals
Drive the new oil seal square with a seal driver, refit the circlip and dust seal.
5. Refill oil
Pour in the specified weight and set the air gap by measurement, not by volume alone.
6. Reassemble and set sag
Refit the legs at equal height, torque clamps to spec and re-set static and rider sag.

FAQ
How much does a Harley-Davidson Softail Standard fork seals job cost?
Around $360 at an independent workshop including parts, and up to $550 at a dealer with premium parts. Doing it yourself costs $120 in parts and consumables plus about 180 minutes.
Is a weeping fork seal an MOT or safety failure?
Yes in most inspection regimes, and it is genuinely dangerous — fork oil on the front tire or brake disc destroys grip.
Should I upgrade springs while the forks are apart?
If the stock rate is wrong for your kitted weight, yes. The labour is already paid for, so springs cost only the part price.
Is a rear shock worth it before tires?
No. Tires and correct sag first; a premium shock cannot fix worn rubber or wrong preload.
