Description

Overview

The Crown Automotive 8126637BC is a 260 series front axle U-joint with a 1.06 inch cap and a grease fitting. It fits the Cherokee XJ, CJ5, CJ7, Comanche, Scrambler and Wrangler YJ. The part is also known as CRO8126637BC.

The joint is fitted at the front axle and has a grease fitting for lubrication. Crown Automotive has made Jeep replacement parts for over 50 years.

The cap size and series are the key facts for matching this joint. Several U-joint sizes exist, so measuring the caps of the old joint before replacement, and comparing the series and the 1.06 inch cap given here, avoids a wrong choice.

The joint has a grease fitting for front axle service. Confirm the cap size against your old joint before ordering. The fitment years run from the mid-1970s through the mid-1990s.

  • 1.06 inch cap
  • Greaseable, for front axles
  • Front position
  • Direct fit replacement part

Greasing and front joint care

Front axle U-joints work under steering angle as well as drive torque, so they wear faster in areas with heavy off-road use. A joint with a grease fitting can be purged of water and dirt, which extends the life of the bearing caps. Pump grease until fresh grease appears at the cap seals, and wipe away the excess.

Look for dry seals, rust streaks on the caps, and play when the axle is lifted. Stiff steering or a clicking sound on tight turns can also point to a worn joint. Front joints are often replaced alongside the axle shafts and the other joint on the same side, since wear tends to match across the set.

  • Grease until fresh grease shows at the seals
  • Check for play with the axle lifted
  • Inspect for rust streaks on the caps

Questions & Answers

What size is the Crown 8126637BC?

Which Jeeps does the 8126637BC fit?

It fits the 1984–1992 Cherokee (XJ), the 1976–1983 CJ5, the 1976–1986 CJ7, the 1986–1992 Comanche, the 1981–1985 Scrambler and the 1987–1995 Wrangler (YJ).

Does the 8126637BC need grease?

Yes, it has a grease fitting for front axle service. Lubricate it at regular service intervals and check the caps for dryness.

Does the 8126637BC fit a Wrangler TJ?

No. The 8126637BC does not fit a Wrangler TJ. Choose a joint that fits the 1997-2006 Wrangler if you own one.

How do I tell a front axle U-joint is worn?

Look for play in the caps when the axle is lifted, rust streaks around the bearing caps, and a clicking noise on tight turns. Stiff steering can also point to a failing joint.

Should front U-joints be replaced in pairs?

It is often a good idea. If one joint on an axle has worn, the other joint on the same axle has usually seen similar use. Replacing both keeps the front driveline working evenly.
