2007 Ford F-150: Rear axle / pinion seal
2007 Ford F-150 · 11th (2004-2008 redesigned, not Heritage) · 5.4 3V Triton, 4.6 3V Triton
What this is
Rear axle and pinion seal leaks are common. A seal is cheap. A noisy differential is not. Whine at speed, gear oil on the belly, or a clunk taking off are reasons to get it on a hoist before you argue about price.
How you’d notice
- Whine at speed
- Gear oil on the belly
- Clunk taking off
- Wet pinion area
Typical shop cost
| Repair | CAD | USD |
|---|---|---|
| Independent shop, parts and labour, before tax | $300–$1,800 | US shop quotes vary |
As of 2026. Ballpark, not a quote for the vehicle in the ad. CAD figures are Vancouver Island independent-shop ranges. USD is only printed when we’ve entered a US shop range — we don’t invent one.
A hoist, not a driveway glance. You pay the shop. First appointment of the morning so the engine is cold.
Mechanic’s tip: spot it before you buy
Look for gear oil on the belly and the pinion. A whine at speed plus wet housing is not “just a seal” until a shop says the gears are quiet.
The bigger picture on this listing
This page is the year and model. The report is the vehicle in the ad. We do not publish, for this listing:
- whether these photos hide this job
- whether the asking price already assumes it
- tax on this price
- a named shop in this city — we only print phones we’ve checked
That’s the $34.99 document. Homework, not an inspection.
Questions people actually ask
Is a wet pinion a walk-away?
A seeping seal is a discount. A whine plus a wet housing is a bigger conversation. Do not price a seal when the gears may be next.
Will an oil change fix the whine?
No. Fresh fluid does not put metal back on the gears.
