The Dana/Spicer Model 35 is an automotive axle manufactured by Dana Corporation since 1985. Originally, the axle was made by American Motors (AMC) as the AMC-15. The first model was made in 1962 and American Motors sold its axle production equipment to Dana Corporation in 1985. Dana upgraded the rear axle and made an independent front suspension (IFS) axle and a twin traction beam (TTB) front axle.
Trucks and SUVs Using Dana 35 Axles
The Dana 35 axle holds up well when used around town. The 1990s Ford Rangers, Dodge Dakotas and Durangos had Dana 35 front axles. The newer Dana rear axle is very popular in Jeeps and was common in the Jeep XJ Cherokee from 1984 through 1997. It was in the MJ Comanche from 1986 to 1992 and the YJ Wrangler from 1987 to 1995. The 1997 to 1998 Wrangler and the 1984 to 1997 Jeep Wagoneer had a Dana 35 rear axle.
Problems With Dana 35 Rear Axle
The Dana 35 became known as a weak axle when paired with tall tires with a height of 31 inches or more. Owners reported breakage with rugged use or when carrying a heavy load. In 1990, the manufacturer switched to a C clip, which did not hold up well either. This issue has been helped by the "Super 35" kit, designed to reinforce and strengthen the axle shaft. However, this hasn't always been a satisfactory solution for many owners, who prefer to trade the rear axle for a beefier, newer and more sturdy Dana 44 axle.
Differences between Dana 35 and Dana 35c Rear Axles
There are two Dana 35 rear axles: Dana 35 and Dana 35c -- "c" meaning custom. Dana shipped the incomplete axle to Chrysler, where building was finished. The two versions have different shafts, bearings and carrier. There is a "C-Clip Eliminator" kit for the Dana 35c. This axle is a bit small for challenging 4-wheeling that requires lockers and larger, rugged tires. Once larger tires are added most owners upgrade the axle.
