Got the coil over and upper wishbone mounts off and will use them on the Willys frame once it gets spread to the same outer width as the Grand. Also got the mounts out from inside the frame for the front of the sub frame. Was a pain as lots of spot welds and stitch welding on the outside.
Decided to remove the rear quarters as hoping to be able to sell them to the Jeep wrecker as nothing wrong with them.
Driver side off.
Passenger side quarter panel off too.
One 1/4 panel. Hopefully can sell it off one day.
Got the firewall on this side mostly unpicked.
The damaged side on the right will be harder to remove as all squashed together. Will need quite a bit of straightening before I can use it, but will be much easier once the kick panel area is gone.
Not much progress to show worth posting about but still forging ahead between other things that get in the way of the project like normal. I made a quick rotisserie out of two Aldi engine stands that cost me less than $100 for both of them. Can't buy the casters for that let alone the thick plate the pivot is on and other steel used in the stands etc.
Lifting up what is left so I can attached it to some raised engine stands I made up to make this next job easier and safer.
Stands are higher than needed for this part of the job but I will use them also for rotating the Willys cab as well.
Had to use the old Pythagoras rule for working out length of the hypotenuse, so I can know how high the pivot point needs to be. Squared the height of the cab, then added the squared width and then square rooted the result. A2+B2=C2 Halved the answer to get where the pivot point should sit and still be able to do a full rotation without hitting the floor. Just as well I paid some attention at school as never know when you may need that knowledge.
Decent sized rails underneath with over 300 spot welds holding just the forward section of the floor I need on. Door sills were very robust as well and a double section. Much drilling to go and then can start drilling out all the suspension brackets and coil and panhard mounts etc too!
As I will be using the firewall and floor, I had to repair the damage from the Harley that hit the side at 100 mph according to police estimates.
Thought it would be easier while still up on the rotisserie for a good working height. Also much easier to flip it up either way depending on which side I am working on.
The ruler gives you an idea how much it needs to be straightened.
This crease is pretty sharp. This photo shows how much the force moved it. You are looking at the firewall upside down and this is where it goes from vertical to curving into the floor section.
Looking a lot straighter now. Need to work the upper section some more but will do that later once off the frame as some buckling still under that section.
Still busy drilling out all the spot welds to remove the floor from the uni-body frame
I have ground the drill bit into what called a pilot point. These only work once a pilot hole has been drilled first. Then the centre part of the drill sits in this to locate the bit and then the cutting edges are almost flat to give a very shallow cut. The angle is less than what shows on this angle of shot.
You can see that all the drill holes on the lower part of the picture is what is left after only drilling the large hole through the top layer of the spot welded metal only. Much easier to just weld the small pilot hole up then the whole spot weld size.
But as you can see there is an awful lot of them to be done!
Finally after 400 odd spot welds drilled out, the floor and firewall is separated from the uni-frame.
Quite substantial as 4" deep and further reinforced with another hat section inside of that as well.
Good to see how well all the galvanized steel is coated through and through. Was even between each layer of steel also.
Will be leaving the floor stiffener in place as it is the rear mount for the seats and seat belts.
I did quite well on drilling out all the spot welds too with one or two one breaking right through the floor panel that I wanted left undrilled apart from the pilot hole. There was a few others when a bracket had to be removed from the top side as well so had to be drilled from both sides, but not bad going when you have to stop the drill bit each time only 1.2mm short of drilling through. Learnt a trick right near the end of tapping in a cold chisel into the joint and then you would here a crack just as the spot weld broke from the floor. Of coarse only discovered this with less than a dozen to go!
Not sure if I can keep where the cowl juts out or not. It was for the air intake for the heater and A/C and where the wiper motor and linkages sit. Not useful for either as they are needed under the cowl in the Willys and not the bonnet where this sits in the Grand.
Still undecided on how to best use the rear suspension mounts. At the width it sits, the rails with upper and lower control arm and coil mounts would nearly fit between the Willys chassis whole. So could leave them mounted to the rails and weld this to the inside of the Willys chassis.
I will keep this section as one piece until I know how to use it best. Want to use the mounts either way and they are made from HSLC ( High Strength Low Carbon ) steel and is 30-40% stronger than normal steel and has a higher corrosion resistance as well.
I think you missed a spot weld, right over there, see that one? jk
Great progress. I think your decision to keep the suspension assembly as one unit is wise. It will help maintain the strength the factory designed into the piece. Have you had any luck selling off the unused parts to recoup costs? I imagine the salvage companies would want a lot of it.
Only sold a mirror and taillights so far only. The Jeep wreakers are insterested but wont give me a price and want me to name it. They not as insterested once they find out that I know the retail costs though! Thought I might as well wait until I am sure I have no use for everything. unless some one comes forward and needs a particular part. Only a few weeks ago the tailgate struts have been reused to lift the floor under the bed of the offroad camper, so who knows where some of it well end up?
Well that is the last of the Grand Cherokee cut up and carried out of the workshop.
Next phase will be bringing the Willys back in and doing lots of comparative measurements to workout how best marry the two!
The poor little shed is busting at the seams! Managed to fit nearly the whole Grand in there apart the rear quarters, roof and rear floor plus the front sub assembly. Cant wait to start taking things back out of there as means I am actually putting things back together or sold some parts I don't need.
Been a while since there has been a clear floor.
Willys going into the workshop. This is why I made my benches fold down easily. Tight, but it fits.
Hard to believe that that engine will one day sit in the Willys.
Ready to be set at the height where I will take the measurements I need before pulling it apart.
