Yukon Gear Chrome Cover For 8.8in Ford
A chrome rear cover is the one axle part people see when they walk behind a lowered Fox-body or SN95 Mustang, a street-truck F-150 or a clean Ranger, and it is also the part that takes the hit when the stock stamping rusts or gets bent. The Yukon Gear and Axle YP C1-F8.8 is the factory-shape cover for the Ford 8.8 inch solid rear axle, finished in chrome. It replaces a leaking, dented or corroded original and dresses up the back of the car at the same time.
Ford's 8.8 is an integral-carrier, C-clip axle. Everything inside it, from the ring and pinion to the cross pin and Traction-Lok clutch packs, is reached through the rear opening, so the cover is both the oil reservoir wall and the service door. The ring gear dips into the oil held behind the cover and slings it up to the pinion bearings, and the cover seal keeps water out when the truck crosses a flooded road or the car gets washed. Any time an 8.8 needs C-clips, axle shafts, a cross pin or a clutch-pack service, the cover comes off, which is why a lot of 8.8 owners replace a crusty original with something that will seal cleanly and look good doing it.
Degrease the housing and drive a few miles. A wet line starting at the cover seam is a cover or sealant problem. Oil at the yoke is the pinion seal, and oil on the brake backing plates or inside the wheels is an axle seal, often from a worn bearing surface. Our Ford 8.8 rear axle problems guide lists the common failures, and the Traction-Lok chatter fix explains the additive and clutch service if the axle grabs in corners. If a howl is the real complaint, the bearings and gears are the job: the Ford 8.8 master bearing and seal rebuild kit covers that rebuild.
Yukon lists the YP C1-F8.8 for the Ford 8.8 inch rear, the ten-bolt cover axle Ford used under 1983-and-later F-150s, 1986-and-later V8 Mustangs, solid-axle Explorers, Rangers with the larger rear, Broncos, Expeditions and the Crown Victoria, Grand Marquis and Town Car. Count the cover bolts before ordering. The Super 8.8 used in 2015-and-later F-150s has a twelve-bolt cover and will not take this part, and the independent-rear 8.8 found in 2002-and-later Explorers and similar SUVs uses a different housing altogether. The smaller Ford 7.5 rear also looks close but has its own cover. If you are not sure which axle you have, read the axle code on the door sticker or send us the year and VIN and we will match it. More parts for this axle are in our hard parts section.
Drain the oil by loosening the lower cover bolts and prying a corner open over a pan. Clean the housing face down to bare metal; leftover RTV is the most common reason a new cover leaks. With the cover off, check the cross pin, the C-clips and the gear teeth, and if you are going after more axle work see the notched 3/4 inch cross pin shaft for 1985-and-older 8.8s or the 3.73 ring and pinion for the 8.8. Seal the cover with a gear-oil-rated RTV bead around the inside of the bolt holes or a reusable 8.8 gasket, run the bolts down in a crisscross pattern, and refill through the fill plug to the bottom edge of the hole with 75W-140 or 75W-85 as your owner's manual calls for. Traction-Lok axles need the Ford friction modifier added unless the oil already contains it.

No. Those trucks use the Super 8.8 with a twelve-bolt cover. The YP C1-F8.8 is the ten-bolt 8.8 cover.
It fits Mustangs built with the 8.8 inch solid rear axle, which covers the V8 cars from 1986 on and many later models. Four-cylinder and some V6 cars used the Ford 7.5, which takes a different cover, so count the bolts and check the axle code.
Ford sealed the 8.8 with RTV from the factory. Use a gear-oil-rated RTV or a reusable 8.8 gasket, and clean the housing face completely before installing.
Use 75W-140 or 75W-85 as your owner's manual specifies, filled to the bottom edge of the fill hole. Capacity varies by vehicle, so filling to the plug is the reliable method. Add friction modifier on a Traction-Lok axle.
No. It is a stock-thickness cover with a chrome finish, built for street trucks and cars. For rock or trail use, a nodular iron cover offers far more protection for the ring gear.
