Dodge Vancharger 1976-84

 Dodge 4wd conversions were "full-time" from 1976-84 and "part-time"  from 1985 to 90. There are substantial changes between the "full-time"  and "part-time" models. However, before ordering parts, scrutinize the  part in question and compare to details  given in this FAQ and in the  parts catalog. A few years on either side of the 1984/85 year split have revealed that some vans have steering and drive train that are not in  harmony with what the parts catalogs say they should  have. Order with  care!
Dodge "Vancharger" Full-time 4wd 1976-84 

Front Axle
 The Vancharger used a Dana 44 front axle housing. With Dodge full-time  W200 style wheel ends. This style of wheel end did not have locking  hubs. The outer axle shaft was splined and attached directly to the  wheel hub. The wheel bearings were pressed on to the back side of the  wheel hub and held in place by a bearing retainer. The bearing retainer  is held in place by 6 12 point 5/16 bolts. Access to these bolts is  through the outer face of the wheel hub. The access hole is located  between 2 of the 8 wheel mounting studs pressed into the wheel hub  assembly. The assembled wheel bearings fit with a "slip fit" into the  steering knuckle. Some vans have had part-time kits installed. The kits  contained spindles/wheel hubs, locking hubs and a transfer case  part-time conversion kits. The conversion kit continued to use the steering knuckles, brake rotors, wheel bearings and retainers. 
 

Vancharger vans all had coil spring type front suspension. The  coil springs were custom made and are approx. 15 inches tall. The  Vancharger  uses similar radius arms and track bars as used on the Ford  Quadravan units. The track bars have a slight bend 6 inches from the  center of the  upper "eye" mount. The rear radius arm brackets on the  Dodge F/T units are welded to the van sub frame
The front shocks  attach to custom made upper shock mount at the top. The lower shock  mount consists of a bolt  and spacer that are mounted into the side of  each radius arm.
The rear suspension retains the OEM 2wd leaf  springs with a 3-3/8 tall lift blocks. The Maxi vans used an additional  1-1/2 lift block in conjunction with the std. 3-3/8 lift block.
The rear axle lower shock mount has a shock relocation bracket welded to it, in order to retain the stock 2wd

Steering
The How ever, used tie rod ends much like those used on W100 and W200 4wd trucks. They are both right hand thread. However, one has a coarse  thread while the other is fine thread. The  tie rod  length is
56.62 inches from center to center.
The drag link is 46.0 inches long, from center to center. Both ends are  1.0-18 right hand thread with the small end of the taper at .675. The  pitman arm end of the drag link is straight. The steering arm end of the drag link has approx. a 3/4 inch offset. The adjusting sleeve has two  clamps which are centered over 1/8 wide slots at each end of the sleeve.
Transfer Case
Full-time 4wd Vanchargers used a New Process 203  transfer case that had a left hand offset. The input gear may be either  21  or 31 spline. The transfer case mounts to a custom extension housing that was designed to fit the stock Dodge transmission 727 transmission. The  extension housing has a foot cast into it. The foot attached to a large U shaped cross member  via two half inch diameter bolts with four split  bushings. The cross member is suspended from the underside of the van.

The 203 transfer case also had a torque mount attached to the left side of the  transfer case. The inner bracket was bolted to the transfer case.  The outer bracket was welded to the underside of the van. The brackets  were connected via two bushings. One large male bushing and one small  female bushing. The torque brackets are lightly built and usually found cracked or completely broken.
The shifter is a complicated  collection of links and hiem joints and allen head shoulder bolts. All  hand a machined aluminum "T" shaped shifter handle.

The speedometer cable has a extension cable approx. 24 inches long. The upper cable is stock 2wd.
There are several different driven gears. They can be identified by color and tooth count.

Transmission
Full-time Dodge Vanchargers had Chrysler 727 automatic transmission.
The original main shaft was  removed, and replaced with a custom shaft..  There were a few different lengths used and well as spline counts. The  most common spline counts are 23 or 31 spline.
