The Dakota 4x4 has independent front suspension. The front axle center bolts to brackets attached to both the frame and the motor. Then there are CVC axles & joints that extend out to the wheel bearing hubs that are attached to upper and lower control arms on ball joints. Torsion bars are connected to the lower A frames and to a bracket back near the trans mount.
Pics 1 & 2 are the best pics I have of the 4x4 Dakota front suspension, but neither show the motor mounts present. The driver side motor mount bracket bolts onto the axle pinion housing with 4 of its 6 bolts. These pictures are from a 92 frame, but the Dakota 4x4 from 1988-2007 use the same set up, The Durango's were slightly different.
The heaviest torsion bars available on a Dakota are for the 2,000lbs front end (a V8 HD version), but the lightest Durango torsion bars support 2500lbs. The books say they don't interchange, but other then the diameter, everything else measures the same and they all use the same adjusting bolt setup (I've measured both a 99 Durango and an 05 Durango bar in the truck). I need heavier torsion bars on my 49 Dodge pickup with a 5.2 (Dakota 4x4 with a 318 46RE trans), probably because the cab sits farther forward then the Dakota sheet metal did. I haven't had a chance to pick up a set of Durango bars to test fit yet, seems something more important keeps coming up.
