Front driveshaft for 1995-2000 GM K1500, K2500, Tahoe, Yukon and Suburban 4WD with the 4L60E automatic. Replaces 26057959, 65-9361 and 938-224.
A clunk every time you pull the transfer case into 4-high, a shake that only shows up with the front axle engaged, or orange rust weeping out of a U-joint cap on a 1995-2000 Chevy or GMC K1500 is usually the front driveshaft. This is a complete, new front shaft assembly for the GM full-size 4WD trucks and SUVs of that era with the 4L60E automatic, replacing GM 26057959 and crossing to Dorman 938-224 and 65-9361. It arrives assembled and balanced, so the job is a bolt-out, bolt-in swap rather than pressing joints into a worn shaft.
The 4L60E sends power to the transfer case, and the transfer case splits it to a rear shaft and to this front shaft, which runs forward along the frame to the front differential. On these trucks the front shaft works at a steep angle because the front axle sits well below the transfer case output, and it spends most of its life spinning in two-wheel drive with little load on it. The listed assembly uses a slip yoke at one end to let the length change as the suspension moves, a U-joint at the other, and a constant-velocity joint to cope with the angle. Spicer notes that a single U-joint run above about three degrees loses life and can cause vibration, which is why the geometry of this shaft matters so much.
With the truck safely supported and in Neutral, grab the shaft near each joint and twist and lift it. Any click, looseness or notchy rotation at a joint means it is worn. Also check for slop at the slip spline. If the vibration happens in 2WD as well, look at the rear shaft, tires and wheel bearings first, and remember that a 4L60E problem such as converter shudder can feel like a driveline shake. Our 4L60E common problems guide helps separate transmission complaints from driveline ones.
The listing covers 1995-1999 Chevrolet and GMC K1500 and K1500/K2500 Suburban, 1995-2000 Tahoe and Yukon, K2500 pickups in the 7200 and 8600 lb GVW ratings, 1996-2000 GMC K3500, 1995-2000 Chevrolet K3500 and 1999-2000 Cadillac Escalade, all 4WD with the automatic. Trucks with a manual transmission or the 4L80E use a different front shaft, and GM used more than one front shaft length in these years, so measure your old shaft before ordering. This one has an installed length of 31.73 to 33.9 inches with a 2.01 inch tube and 0.118 inch wall. If yours measures outside that range or you are unsure, send us the year and VIN. Other parts for these trucks are on the 4L60E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The listing covers automatic-transmission 4WD trucks only. Manual-transmission trucks and 4L80E trucks use a different front shaft.
With the truck at ride height, measure from the center of the joint at the transfer case to the center of the joint at the front axle. This shaft has an installed length of 31.73 to 33.9 inches. If yours falls outside that, it needs a different shaft.
No. The assembly is new with its joints installed and is balanced as a unit. Grease them at install and at every oil change if the truck gets used in 4WD.
In 2WD the front shaft spins with almost no load. In 4WD it carries torque, so a worn joint, a bent tube or play at the slip spline shows up as vibration or clunking only when the front axle is engaged.
No relearn or transmission work is needed. The 4L60E only connects to the transfer case. If you also have shift or slipping problems, those are separate transmission issues.
