2016 Ford Explorer PTU (AWD Transfer Unit) Failure: What It Really Costs to Fix
Quick answer: 2016 Ford Explorer ptu (awd transfer unit) failure typically costs $150 to $2,800 at an independent shop, depending on which component failed.
Applies to: 4WD/AWD only. Other versions of the 2016 Ford Explorer do not have this problem.
What the Issue Is
Four-wheel-drive fifth-generation Explorers use the same transverse all-wheel-drive layout as the Escape, scaled up, and the Power Transfer Unit carries the load of a three-row family hauler. Its small fluid volume rides beside exhaust heat, and when that fluid overheats and breaks down, the gears and bearings follow: whine, seeps, a burnt or odd smell, then grinding and replacement. Towing duty speeds all of it up.
Ford documented the heat problem in SSM 47230: AWD Explorers, among other 2007 to 2016 Ford and Lincoln models, built on or before June 30, 2016 may give off a propane or natural-gas-like odor at idle or low speed because the PTU fluid breaks down from excessive heat. Where the unit can be saved, Ford's fix is an idler gear and bearing repair kit (GB5Z-7P258-A); a unit too far gone is replaced. On an Explorer owners' forum, one owner reported a dealer quote of about $1,900 for a whole unit, while seal leaks can be a much smaller job.
Buyers should treat the PTU as a named line item in any AWD Explorer inspection: housing condition, odor at idle, fluid history and a whine test, alongside the water pump that shares this truck's risk list.
Symptoms to Watch For
- 1.Speed-tracking whine or howl from underneath
- 2.Propane or natural-gas-like odor at idle or low speed (overheated PTU fluid)
- 3.Burnt gear-oil smell after highway driving
- 4.Fluid seep on the PTU case near the passenger axle
- 5.Grinding or bind in tight low-speed turns (advanced wear)
Real Repair Costs
Prevention versus replacement, Explorer-sized: a repairable unit can take Ford's idler gear and bearing kit, while a new or remanufactured unit installed sets the top of the range. Towing histories push wear earlier.
| Repair | Typical Cost (installed) |
|---|---|
| PTU fluid drain and refill | $150-$250 |
| Seals + fluid service | $350-$700 |
| PTU replacement, installed | $1,500-$2,800 |
Moderate issue. Ranges are US independent-shop estimates with quality parts. Use them as negotiation grounding, not a quote.
Mechanic's Tip: Spot It Before You Buy
Same routine as every transverse-AWD Ford, with higher stakes: on the lift, inspect the PTU housing beside the passenger-side axle for seepage and heat-baked residue, and take a sniff around the front of the idling truck, because a propane-like smell is the overheated-fluid symptom Ford's SSM 47230 describes. Ask for any record of PTU fluid service or the idler bearing kit. Drive with the radio off listening for a whine that tracks speed, and load the driveline with a few full-lock parking maneuvers, feeling for bind. On tow-package trucks, assume harder duty and price accordingly.
The Bigger Ownership Picture
Beyond this specific issue, budget roughly $1,200-$1,700 per year for scheduled maintenance and repairs on a 2016 Ford Explorer. That is a typical US range from Avturo's ownership-cost table, an estimate rather than a quote, and it excludes insurance, fuel, and financing.

Frequently Asked Questions
How much is an Explorer PTU replacement?▼
About $1,500 to $2,800 installed at independent shops for a new or remanufactured unit, depending on the part; one owner reported a dealer quote of about $1,900 for a whole unit. Seal-and-fluid rescues run $350 to $700 when caught early, and a fluid change costs $150 to $250.
Why do Ford PTUs keep failing?▼
Heat. A small volume of fluid sits beside the exhaust, and Ford's SSM 47230 traces a propane-like odor on 2007 to 2016 AWD models (Explorer included, builds through June 30, 2016) to PTU fluid breaking down from excessive heat. Degraded fluid takes the bearings and gears with it, which is why the fluid's condition is the best single clue to a unit's health.
Can I prevent PTU failure on a used Explorer?▼
If the unit is healthy today, fresh fluid is the cheapest protection: change it after purchase, look at what drains (clean is good, black tar is bad), and repeat periodically, more often when towing. A quiet, dry PTU on fresh fluid is a far better bet than one with unknown history.
Is AWD worth the risk on these Explorers?▼
For buyers who need it, yes, with the PTU inspected and serviced, the system is dependable. For fair-weather drivers, front-drive examples remove both the PTU and rear-driveline maintenance from the ledger entirely, and they are common in the used pool. Match the drivetrain to your actual winters.
