Rebel's Charger thread

Post by Rebel »

Thought it was about time I started a workshop thread for my '68 Charger.

As there has been a couple of threads recently about steering, I reckon a good way to start is to show the conversion from power steering to manual, just finished this a few days ago.

To start with, my power steering box was worn out, I had adjusted it as much as I could, so much so that any further adjustment and the steering would become notchy when steering. it was ok when driving at under 30mph but anything over this and it would wander, on the motorway it would want all three lanes. Add to this how light the Mopar power steering is, the lack of feedback from the wheels when driving and after talking to a few people on here, the decision was made to switch to manual steering.

This is how I did it, the first pic shows the original set-up, standard Mopar coupler connecting power steering box to power steering column.

The bit circled in yellow is the crimped metal lid that goes over the orange rubber seal on the top of the coupler, it also shows the spring clip that some dealerships fitted to prevent the coupler coming apart while driving :shock: both the crimped metal lid and the spring clip (if you have one fitted) need to be removed to allow the column to be separated from the coupler.
The bit circled in red is the steering column bearing, the screw circled in green goes through the hole circled in green in the top of the pic, mine was seized solid, more on this later.

Next job was to unbolt the steering column from its supports inside the car, this consists of removing 7 bolts and 2 nuts. In the first of the three pics below you can see 2 of the bolts outlined in green, these are at the bottom of the steering column, where it goes through the firewall or floor pan, they both need to be removed.

The second pic shows the lower steering column support bolt, outlined in blue, this is the most difficult one to get to. It's hidden up under the dash board and is easiest to see if you lie on your back with your head on the floor next to the brake and accelerator pedals and use a torch to see it.

The final pic in this section shows the remaining 4 bolts and 2 nuts to remove and are probably the easiest ones to take out. Remove the 4 bolts, outlined in red first, this stops everything dropping and becoming awkward to hold while you remove the final 2 nuts.
The 2 nuts outlined in yellow can be removed now - these are all thats holding the column in place at the moment and as you undo them the whole steering column will start to drop down. Once you've got them loose enough to turn by hand, use one hand to support the column itself and the other hand to remove the nuts.
The 4 bolts outlined in red also hold the steering column to the main column support, this will fall as soon as all the bolts (outlined in red and in yellow) are removed. You might have to take hold of it and jiggle it a little bit to free it, there's a small multiplug connector at the base of it, you could disconnect this and move the metal support out of the way altogether but there's no need too, I just left the frame resting on the brake pedal.

Now, hold the steering wheel in both hands and pull gently back towards yourself, you only need the column to move by a couple of inch's, rest the steering wheel on the cushion of the seat and leave it there for now.

Back under the bonnet (hood :D ) and it's time to remove the steering shaft pin, outlined in yellow in the below pic. It should just knock out using a hammer and a punch of some sort (large nail, old screwdriver etc), the pin is a very, very tight fit though. I used a length of 1 inch hollow box section steel tubing with a "V" cut in the end as a support under the pin, this meant I could hit it with a hammer without damaging the column. Once the pin was flush with the end of the column, I put a small dimple in the end of the pin using a grinding stone on a Dremel type tool. I found that as I was doing this with the column still in the car, I couldn't hold a punch of some sort and get enough of a swing to hit it hard enough with a hammer. I ended up using the pointed end of an old chipping hammer resting in the dimple of the pin, being able to hold this in place by it's handle, gave me the ability to get a good swing at the opposite end of the hammer head, the pin was drifted out - eventually.

Moving on to the power steering box itself, disconnect the 2 pipes from the power steering box (the high pressure and the return), have a container ready to catch any fluid that leaks out. There are 3 bolts that hold the power steering box to the chassis / K member, outlined in red in the pics below, 2 to the right of the steering box and 1 to the left ( as you look at it from the side that the steering column connects to ). All 3 bolts need to be removed.

Thats all for now, I'll put the rest of the process on tomorrow

Before removing the bolts that hold the steering box in place, disconnect the pitman arm from the steering box, I used a pitman arm puller, gets the arm disconnected in seconds.
According to the manual, the power steering box from a Charger with a 383 engine can be removed from under the car once all disconnected, this isn't the case. After some help from members on here, the exhaust header was removed, the oil dipstick tube and the spark plug leads had to be disconnected (didn't need to unbolt the engine mount and lift the engine though), this allowed the old power steering box to lift out.

Now, the fun part, putting it all back together.

The manual steering box is about half the size of the power steering box so goes in easily compared to the power steering box coming out.

As the manual steering box is about half the size of the power box, when its fitted and the steering column is temporarily bolted back in place it leaves a gap to be filled between the steering column and the steering box as can be seen in the pic

To join the manual box to the power column, use a power to manual coupler from Flaming river, this is what you get in the kit

Slide the universal joint in to place on the steering box shaft, using a screwdriver to hold the coupler in place on the steering column ( poked through the hole in the steering column that the shaft pin was knocked out from and the corresponding hole in the coupler ), with everything in place, measure how much of the coupler shaft needs to be cut off, then measure it again, and again just to make sure it's right

The picture below shows the measured (3 times :D ) mark that needs to be cut, outlined in red

The final cut was made using an angle grinder, the part outlined in red is all that was going to be used.

Once the cut has been cleaned and dressed, the coupler can be connected to the universal joint to complete the new coupler

The new coupler can now be trial fitted to make sure all the measurements were correct and that everything fits together

Having made sure that everything fitted properly, it was all bolted permanently in place. The red outline in the pic shows the roll pin (supplied in the kit) that gets knocked into place through the coupler and the steering column. Being overly cautious, I put a split pin through the roll pin, more for peace of mind than anything else.
The yellow outline shows the new steering column bearing bolted in place.

Now that its all done, the power steering pump can be removed as it's no longer needed.

That's it, all done, my charger now has manual steering. Hope it all made sense and was easy to follow without being too boring :thumbright:
