seems like I have been doing a lot of shop work, (truth is much is maintaince),
the Buick century 1991, been a good car for us, has 215,000 miles on it,
two problems one wife went to town and had some problems with it running and keeping running,
it needed a new crank sensor, the problem was the first one was faulty as well, and ended up changing the coils, and coil controller, wires and sparkplugs, much new wire loom, and a second crank sensor, it is running good now,
a tire was wearing on the front, ended up replacing the lower ball joints, it was a more frustrating job than I thought it would be, (ended up compressing the coil springs and then had the clearance to work on it.

then went to check the alignment on it, and the alignment level was to large to fit on the hub, so I ordered a Joes billet gauge, with a magnet adapter,
the cup in the adapter would not fit over the axel stud,
I did put a die over the axel and was able to do a quick check on the alignment and it was passable,
the next day I turned a new adapter out on the lathe and rechecked it a few days later,
mounted new front tires on the car, (I use air soft BB for balancing beads), they work wonderful on the dirt and mud and snow were having. as the rims are constantly packing with foreign materials and the balance is changing.

was having a lot of door problems on the S10, finally got a latch for it and now works good, the hinge is still a problem, need to pressed back in the top hinge is pulled out some, they have new bushings in them.
need new front tires on the S10 as well,
did the ball joints on both sides, Had a hard time on the lowers, (really do not think the replacement joints were the correct size, pressed in very very hard,)

went to align it and all the tire rods are going, did get the caster and camber back in fairly close, (it has about 160,000 on it), ordered a complete tie rod group, most likely next week I will be putting that on,

but seem like I have been working on the cars and trucks a lot as of late,

I need to get both one tons in the shop and work on them the 1978 needs a new neutral safety switch and the door latch adjust, need new running lights on the cab,

the 1980 needs new springs on the front, and running light on the cab,
really the 1980 needs the engine rebuilt, but currently no a big need (just used around the farm here).

been keeping busier than desired on the cars, and trucks the last month.

Definitely seems like lots of good work & fun to be had at your place!
Geez I got one car and a 4x4 and I can barely keep up too!
What brand of crank sensor did you get that was bad out of the box?
I generally will only get Delco/Delphi from now on..

I do not even know the brand now, I bought it from Rock auto, on a close out deal, did not cost me much $ I think it was like $6 on the close out, and original about $45 was the normal price, , but I ended up going with a Delco unit. and no problems, (my be the quality of them were why they were being closed out).

between the tractors, and the car and trucks I can keep the shop busy,
have my own tire machine as well, and that can keep one busy at times, most of my stuff is old,
the F500 is a 53 (dad bought it new), and the GMC 6x6 is a 52, the one tons are 78 (only one bought new), and 80 was given to me, have it set up as a welding truck,
have a 78 van but do not need it so it has just sat the last few years, it has about 300000 miles on it, good old van, yet,
the 91 buick I got from a junk yard, my son was broke down and waiting for parts for his truck and for some income he was cutting steel at the scrap yard, and this person brought in this Buick, (the guy had just got out of jail and need some money) my son looked it over and called me and said the junk yard bought for $125, and would sell it to me/my son, for 125$, and if it was no good bring it back and he would buy it back for $125 it had a little less than 100,000 on it, had to put an alternator in it, and tires on it, and we have about 215,000 on it (had had to work on it a few times but nothing major. get right at 30 MPG, and is a fine little car,
the 91 S10 was my dads before he passed on, and my mother gave that to me, I have put about 50,000 on it my self and it has about 160,000 on it,
so for the most part all I am doing is really maintance on them.

I have a few other trucks on the place that could be made to run, (my old 1970 4x4 chevy halve tone pick up dad bought new and I do not know how many miles are on it, the majority of it life has been spent off road in the pasture. guessing 250,000 miles on it most at under 10 mph and off road, (one day I had four flats on it in one day), working fence, (it would go through tires with the cactus and brush in the pastures,
I ended up getting recapped air craft tires (I think the side walls are 12 actual ply'* and the tread area about 24) I had a set of vale stems rot out but no tire flats on it after that, it needs a ring gear in it,

yes it seems like I end up working on cars trucks and tractors a lot on my place,

They dont make things like they use to. I like the older vehicles but dislike carbs.
Did the 53 f500 come as a flat deck? (love the grille on them)
Hang on here.. you got a GMC Military 1952? What shape is it in?
I really like the story on the 91 Buick..one alternator & tires and your good to go to for the next 115k = awesome.
Sound like you for off road you could really use the new Kevlar tires, like I run on my 4x4- GY Silent Armors.

the 6x6 is in good to fair shape, it has about 14000 miles on it, I used it some for about 15 years, the farm hauling grain, but it is actually cheaper for me to hire the grain hauled to town than to feed it fuel,

at one time I used it to haul form the field to the bin, but now I just park it at the auger and use it for a pit, and run the combine up to the truck,

it is a gasser, it has a 302 cubic in engine, a redone 270 (I think) basically the same as the ww2 2.5 ton 6x6,

then it has a hydramatic automatic 4 speed transmission, with a two speed planetary reducer behind the transmission then a single speed transfer case,

it has air assisted hydraulic brakes, (the ww2 had vacume assisted power brakes,

My under standing is that the axels and much of the running gear is the same as the ww2 GMC truck,

the weak point of this truck was the automatic transmission, I rebuilt it once, and added a power shift kit , one manualy selected the gear, helped a lot,
I got the kit form a surplus company in Memphis Tennessee, they made this kit,

the bad thing is I do not run it enough and to get the brakes up and everything working correctly some times takes a day or so, so I have not run it for a few years, (it has a grain gravity box on it, it has about a 250 bushel capacity,)
~~~~~~~~~~~~~~~~~~~
the 53 F500 dad bought new, I think was bought as a cab and chassis unit, and a grain box was put on it after delivery, it has a hoist, I keep it licence and insured, and it gets to town a few time a year, it holds about 160 bushels,
the odometer has sat at 65000 miles, ever since I can remember, Have no idea the mile it has on it, actually the truck is in good shape yet, had to put new tires clear around on it, (the front was old odd sized tires) I found some that had been made in the original Firestone molds the old logo and even had the guys name who built the tire on a sticker on each tire, they were not cheap, I got rid of the widow maker rims, and have locking ring rims on it,

the engine has been swapped out with a 390 V8, in the early 80'* JC witney had some adapter bell housings for making street rods out of the old pickups, and I ordered one and replaced the flat head, dad had the flat head worked on, and a few of the valve seats came lose and beat up things bad, so the engine need to be replaced, any way, I bought a old Galaxy with a 390 in it and just pulled it and put it in the truck. cut the cross member of the car for mounting the engine in the truck, used the original truck radiator an then put a few resistors on the heater fan and swapped out the bulbs for 12 volt.

"Cut the cross member of the car for mounting the engine in the truck"
I had to think about that for a while. Did you know right away by measurements the cross member would fit?
I suppose you use what you got & adapt the cross member makes total sense.
Sounds like a big welding job though & a tricky alignment.

I had the car in the yard when I was working on it and for the most part, I pulled the old engine swapped out the bell housing. and I think I lowered the ending in and temporal y bolted it up cut out the cross member that the engien was mounted on,
(with out going and looking, and it is currently blowing and snowing), I think i cut it in half as it was also part of the suspension support on the car, taking the top half and bolting mounts to the engine (with some measuring cut it so it lapped on to the truck frame and checking alignment, what I remember I lower it to the frame and tack welded on one edge, (don't know why but the drivers side was up about a 1/4 of an inch (I could have cut and make fit but it was easier to slip a shim of 1/4" strap under it and weld it, (I pulled the engine so I could get a good weld on the the member and then put the engine back in for good, hooked up the wiring and (I did move the battery out from under the floor) and made a mount on the passenger fender, make batter maintenance much easier IMO.

and rebuilt the exhaust system, and need to plug off one side of the radiator pipes,

one thing is there was room to work in most of the older vehicles, so it was not a real hard project, being able to get the bell housing was the key to the project, and I think that was the last year they (JC witney) offered the bell housing, before the internet finding things was not always easy,
