Our dog-tired '68 Barracuda...
Our dog-tired '68 Barracuda had a well-worn front suspension. One of the best upgrades on any old Mopar is to freshen the underpinnings up front with a complete rebuild. We had the engine out of this car for a rebuild, so it seemed like the right time to go through the suspension.
Quite some time ago we introduced our ragged '68 Barracuda fastback. The tired old beast was put on the road with a minimum of wrenching-just enough to get it going. With its rat-rod flat-black primer and stripped-out interior, it was the perfect machine for slummin' in style. We got the itch to make it a little better though, and out came the well-worn 318 for a buildup. With the engine out, it seemed like the right time to get other mechanical matters up to spec. Though the rear suspension had been thoroughly rebuilt, up at the front, things were downright sloppy. With more power on its way, it was time to bite the bullet and do a full rebuild of the front end.
Suppliers, such as PST, offer complete suspension rebuild kits, providing all of the normal replacement components in one box. With a kit, the front suspension and steering can be stripped out and fully rebuilt to as-new freshness. We strongly prefer this comprehensive approach, rather than replacing parts piece-by-piece. PST offers bushings in either stock rubber or their proprietary PolyGraphite material. We opted to get a mix of the two, going Poly for the strut rod and upper control-arm bushings, while retaining rubber for the lower control-arm pivot bushing. New upper control-arm adjusting cam-bolts were provided in our kit, and we noted that the design had been beefed-up considerably from the replacements offered a few years back. To complete the parts selection, we ordered a complement of components to renew the steering linkage, including all the tie-rod ends, a set of heavy-duty tie-rod adjuster sleeves, as well as the pitman and idler arms. Rounding out the kit for our application were new ball joints and fresh rubber bumpstops to replace the battered originals.
Long term, we really aren't sure of what direction we want to go with this fastback fish. On one hand, we like the idea of building a fast drag car, taking cues from the SS/AA package cars that made this particular body style famous. Big-block, full cage, Hemi scoop, and 9-second performance-it would definitely make a statement. On the other hand, a nice fastback 'Cuda street machine with a warmed small-block, overdrive tranny, and a few chassis upgrades would be tough to top as a driver. We're leaning towards the first option, and as a step in that direction, we tapped Competition Engineering for a set of 3-way adjustable drag shocks. We may change directions before it is all said and done, and welcome your comments in helping us decide.
The front end of this original...
The front end of this original 318 machine was the basic package, including drum brakes and no sway bar. We may follow through with higher performance upgrades later, but for now, we just needed to eliminate the unnerving wiggle in the loose components. Rather than going after the parts replacement piece-by-piece, it's best to just order a kit and replace all of the wear components.
To take care of business,...
To take care of business, we ordered a complete kit from PST, and upped the ante with PolyGraphite bushings for the upper control arms and strut rods. We decided to use the stock-style rubber bushings on the lower control arms. These parts will basically replace all of the wear components (one side shown), including the upper and lower control-arm bushings, tie-rod ends, upper and lower ball joints, strut-rod bushings, and camber adjusting bolts. We noted that the camber adjusting bolts have been upgraded from those previously offered; these were nice heavy-duty pieces. We also got fresh pitman and idler arms (not shown).
The first step after securing...
The first step after securing the car on jack stands and removing the wheels is to fully unwind the torsion-bar adjustment screws, located under the lower control-arm. This will relieve the spring tension from the suspension.
Since the tie-rod ends were...
Since the tie-rod ends were worn out and will be discarded, we used a pickle fork to separate them from the steering arm. To use the fork successfully, always align it so that it is working straight back into the steering arm. otherwise the deflecting steering linkage will absorb the force.

After removing the wheel-bearing nut, the brake drum was pulled off, followed by the backing plate with the brake assembly.

We used the pickle fork again to separate the upper ball joint. The upper control-arm was then unbolted and removed.

Next, the shock was removed. It anchors to the lower control arm with a thru-bolt, and a bayonet through the inner fender apron.

The spindle was then unbolted from the lower ball joint/steering arm. One of these bolts in early A-Body drum-brake spindles, threads directly into the spindle. Note the rounded head of this bolt, and reinstall it in the same position.

Our handy pickle fork was employed once again, to quickly separate the lower ball joint.
