Constant Velocity Front Driveshaft Parts for 1975-1993 Dodge Ram Full Size 4x4 Trucks
We stock the world's most complete selection of front Double Cardan CV driveshaft parts for 1975.5 to 1993 Dodge full size 4x4 vehicles. For a little history: Part way through the 1975 model year, Dodge made a supplier switch for front Double Cardan Constant Velocity Joints used in the firm's full size 4x4s from Dana Spicer to General Motor's Saginaw Division. The new shafts retained the same size tubing as the previous shaft, but the CV Joint was GM's new, serviceable S44 Double Cardan Constant Velocity Joint. The slip joint for the new shaft was supplied by Chrysler's own Detroit Universal Division who also made the front universal joint. An interesting feature of the S44 CV head was the use of plastic (continued below.....)
Driveshaft Identification
  The original equipment front CV driveshaft used on 1975-1/2 and all 1976 to 1993 Dodge and Plymouth full size 4x4 models used a Saginaw Double-Cardan Constant Velocity joint at the transfer case end and a slip joint mounting a Detroit Universal internal c-clip universal joint at the axle end. The CV parts remained unchanged over the entire 18 year production run, however, the slip joint will vary after 1985 and the front universal joint changed in 1993 for trucks powered by the Cummins Diesel engine.  

Click to Enlarge		 CV MOUNTING FLANGE: The QU40761 mounting flange on Saginaw Double-Cardan CV Joints as used with original equipment 1975-1/2-1993 Dodge front CV shafts can be identified by the following features:
5" outside diameter, 4 bolt Round Flange mates to the Transfer Case Output Flange using 4 QU10806 7/16" Bolts that fit through holes in CV Flange and thread into your Transfer Case Output Flange. Note: If you have a CV mounting flange is half-round, your driveshaft has an aftermarket Spicer type CV head.		  

Click to enlarge 		CV CENTER YOKE: The Saginaw CV Center Yoke has squared off ends. The 1-1/8" diameter holes for the u-joints have a 3-1/4" center to center dimension. Plastic injected into grooved machined in the yokes and u-joint cups retains the factory installed universal joints. TK40725 and QU40758 replacement universal joints are kept in place by spring steel C-Clips that fit in a groove machined on each u-joint cup. When installed, the C-Clips will be against flats machined on the inside faces of the yokes. Note: If you have CV u-joints with external snap rings, your driveshaft has either been through a major rebuild or it is an aftermarket replacement driveshaft assembly.  

Click to Enlarge		 FRONT U-JOINTS: Until 1993, the front universal joint in the slip yoke was always a dinky Detroit Universal 7260 series which has 1.078" diameter cups with internal C-Clip lockup. 7260 yokes measure 2-1/8" between the inside machined flats of the yoke. 1993 Diesel trucks (and possibly some very late 1992 models) have a larger Detroit 7290 series universal joint with 1-1/8" diameter cups and internal C-Clip retention. The inside span between the slip yoke ears will measure 2-5/8". Note: If you have a front u-joint with external snap rings, your driveshaft has either been through a major rebuild or it is an aftermarket replacement driveshaft assembly.  

Click to Enlarge		 SLIP JOINTS: Up through January 2, 1986, the spline size for Slip Stubs and Yokes on factory assembled shafts will be a 1-1/4"-16 with an external slip yoke seal. From January 2, 1986 to March 28, 1988, several combinations can be found all of which should have a rubber protective boot. Starting on March 29, 1988 all factory front CV shafts use a 1-9/32" fine spline stub and yoke shielded by QK3078 Boot. Note: You may also find 1-3/8" 16 spline slip yokes on rebuilt or aftermarket replacement CV driveshaft assemblies.  
Verify Your Parts Before Ordering!!! VERIFY YOUR PARTS: Given the age of this era of Dodge trucks, it is not unusual to find non-standard components particular with the 1986 and older models with 1-1/4" diameter slip joints using a press on seal. A great many of these trucks have had the original slip joint replaced with 1-3/8" diameter 16 spline aftermarket parts. We also see a lot of shafts with internal/external snap ring conversion joints and a fair number that have replacement shafts made with Spicer style CV components (these will have a half-round CV flange). YOU MUST VERIFY what parts you have before ordering! If you are not sure you have a factory driveshaft, e-mail us some clear photos!

Boots and Boot Clamps
n Dodge switched from slip joint seals to much more effective slip joint boots in 1986. The QK3078 Boot we carry fits some 1987 model trucks and about all the 1988 to 1993 trucks with the original driveshaft slip joint. Most Boot Protected Slip Joints will last the life of the vehicle as long as the Boot and Clamps are in good shape.

Double-Cardan Constant Velocity Parts
n The now obsolescent Saginaw Double Cardan CV Joint used by Dodge for 1975.5 to 1993 full size 4x4 trucks was quite durable as long as the CV Centering Ball was greased every now and again. Strength wise, it is comparable to the more modern Spicer type 1330 series CV shafts used on 1994 and later Dodge Ram trucks. The simple Saginaw centering ball and socket is easier to grease, longer lasting and cheaper to repair than Spicer CV Ball that uses needle bearings especially under poor maintenance conditions. However the Spicer type CV can run at a greater angle.

Driveshaft Assemblies
n The original 1975.5 to 1993 Dodge front Double Cardan Constant Velocity driveshafts used a Saginaw CV Head and a Detroit Universal Slip Joint. While it is still possible to fabricate a new shaft with a Saginaw CV, cost wise, it usually makes more sense to either rebuild an original shaft or replace it with a new shaft built using Spicer Style components. We will list any rebuilt shafts we have in stock below, plus we have a heavy duty unfinished 1350 series CV shaft primarily for those you with Cummins Diesel powered trucks.  
QU40806 Unfinished Heavy Duty 1350 Greaseable CV Shaft Assembly is the lowest cost way to replace your worn out original series oem shaft with a beefed up brand new, totally greaseable, 1-3/16" cup size 1350 series Double Cardan Constant Velocity front driveshaft for your 1975 to 1993 Dodge full size 4x4. The CV Head is already welded to the tube, so all you have to do is determine what length to cut the tube before finishing the assembly. Welding and other machine shop skills and equipment is required to complete assembly!!!! Made in U.S.A. Shaft includes QU40846 1350 series greaseable CV Head, 1330 series greaseable Front universal joint, QU40843 Slip Stub, QU40845 Slip Yoke, QU40832 Tube Length is about 20".

Slip Stubs
n Dodge used a 1-1/4"-16 full length spline Slip Stub manufactured by Detroit Universal from mid 1975 to January 2, 1986. From that date until March 28, 1988 a different Slip Stub was used. Starting on March 29, 1988, Dodge Front CV Shafts used a 1-9/32" 29 spline based on 30 spline Stub. None of these original equipment Slip Stubs are readily available, however, one usually finds worn stub splines also mean worn yoke splines so you normally replace both the slip stub and yoke with 1-3/8" 16 spline replacement components.  
QU40740 16 Spline Slip Stub is used along with either QU40770 Slip Yoke (7260 U-Joint) or QU40854 Slip Yoke (7290 U-Joint).

Tools
Most CV and universal joint service is done using makeshift tools and hammering on the parts until something gives service methods. Driveshaft parts and universal joints are incredibly precise components that can be easily damaged by such slam-bang work. There is a better way to perform driveshaft service using application specific press tooling and approved service procedures. Yeah, I know the Manuals and Tools are expensive, but when you consider that a poorly installed front u-joint blowing out as you tool down the Interstate at 75 is going to cause an expensive and dangerous mess. I have witnessed several driveshaft failures in vehicles driving ahead of me during my travels and I can tell you a 3' long front driveshaft can do a heck of a lot of damage as it whips around jamming into the road, whacking the transmission, and smashing the floor!

The S44 CV Joint was used unchanged all the way through the end of the 1993 model year on all Dodge and Plymouth full size 4x4s through 1 ton size. Detroit Universal supplied the slip joints for all those shafts, but there was several design changes over the years. Dodge was the last 4x4 manufacturer to utilize the Saginaw S44 CV Joint, replacing it for the 1994 model year with a Spicer type 1330 series CV joint. (Back to Start)
