Re: 1974 M151A2 Project
OK, I'll be tackling the bushings this weekend.
In the meantime, here are some images of note. The fuel tank does not have a removable cover but is a pressed portion of the top half of the tank proper. There are all of the fittings to indicate this is an emissions tank, but I have not seen one like this before.

Next is the emissions air cleaner. This has been short-circuited by the previous owner, and the vent distribution canister from the firewall is missing.

Lastly, a view as to the altered ride height. Both the front and rear ends were lifted, but in disassembling the front to replace the wear items, All I can determine is that over-length shocks were used rather than OEM replacements. The distance between the top of the tire and the bottom of the fender is almost eight inches.

Re: 1974 M151A2 Project
Shocks alone will not change the ride height, there have to be other things involved like different springs or in the front maybe spacers between the suspension cradle and the frame. Same with the rear, if it is altered in height then different springs had to be used. The axle u-joints will be very short lived if that is the case.

From what I can make out those are 15 inch wheels and tires, that will give it the lifted look, the rims should be 16 X 7 and the tires should be 700 X 16 or a civilian equivalent 16" tire that is for a narrow rim.

Re: 1974 M151A2 Project
Aren't those rims off of a CJ?
Re: 1974 M151A2 Project
Dan, Cobra5, thanks.
The rims are indeed 15 inches. They came with the jeep, so origins are unknown.
I measured the uncompressed coli spring from the left-front station and it is 13 inches long. Stock?
I received replacement front shocks (OEM from Monroe courtesy of RAPCO) today along with the new bushings. Question: The new shock seems to be stuck at its shipping length; that is, there is no movement up/down when I try to compress it. Is there a trick to this I'm not aware of? Also, the vast difference in length is shown in the below photo.
Ideas?

Re: 1974 M151A2 Project
Ideas? Well, you are taking an antibiotic................ Sorry, I always look around, garages are my favorite but I also like to see who else has to take handfuls of old peoples drugs.
Your new shock is fully compressed, put one of the washers and a nut on it on it without the bushing. Only need a couple threads and then you have something to hold on to. You may have to pull fairly hard to get it going the first time. It also appears that the other shock is not fully compressed. I cannot speak to the length of the spring but it has been listed on here before. You may try a search for "spring length" or Suspension spring length". Meanwhile someone may chime in with it. If it is indeed longer than stock do not run it with the new shock or it will rip the shock apart.

Re: 1974 M151A2 Project
Good info re the shock. The coil length has been listed as 11" for front springs. That suggests that the front (and probably rear) coils have been replaced by longer items.
Getting the right length coil, proper shock, new bushings, a GI rim and correct tire should bring the current height down to the correct level.

Re: 1974 M151A2 Project
Yes Jim the front springs are 11" you also have the right new front shocks showing in your pic, I have a new set of nos rear springs I will measure for you and let you know the lenght .
Re: 1974 M151A2 Project
I appreciate the information on the spring length. It will be easier to trim the current coils than replace them. Since I'm working on the front end currently (and progress is always slower than anticipated..... is a contractor doing this??) the info for the rear springs will gointo the "I'm-a-gonna-do-it-someday" file.
Happy Army Birthday to all Soldiers, prior and current service!!!!!

Re: 1974 M151A2 Project
Be careful with just trimming the springs down because the spring rate could be different also. If the spring rate is too high you still take the chance of pounding the shocks out, not to mention having a really bad ride. The diameter of the coils and the spacing between the coils will give clues to the rate.

Re: 1974 M151A2 Project
A new day, a new discovery. The added height of the truck is apparently based on the two inches of added coil to the springs by virtue of someone welding a bonus piece of coil to the stock piece. When the added piece is measured, the overall length of the original piece comes in just at 11 inches, which is where it should be. Great, something else thrown on the to-do pile.......

Re: 1974 M151A2 Project
Welding a coil spring to a coil spring! I can't believe it did not break. You should be able to safely cut it off right at the weld.

Yeah, it's something like a truck you'd find at Mad Max Thunderdome........... Can't find the right part, we'll just cobble something together......
