OK, I was hoping for more progress but another setback.

The modified coil spring was returned to its normal length by slicing off the welded-on addition. The upper A arm had the old bushings removed (air chisel did the trick), but the arm was apparently bent along the curved shaft that bolts to the crossmember. The two mounting holes no longer match up.

A look at the shaft shows that there is a bend that isn't supposed to be there. I measured the inside distance between bushing openings, finding 13 1/4" on the still-installed side, and 13" on the re-bushed side. My guess is that the arbor press had a tough go of it and warped the shaft/arm when pressing the new bushings into place.

Now it's another un-planned purchase pending, for a replacement upper A arm (with bushings already in place!).

Sigh. :(

Well, as with most of us, life has been taking away the spare time.

The friend who has been working the control arm bushings now finds himself as the only mechanic at his shop, down from four, with no decrease in customers. This means that the favors typically realized when needing the services of air tools and presses have come to a halt, along with my progress.

I purchased replacement control arms with the bushings installed, based on the damaged sustained in the previous attempts to replace just the bushings while retaining the shafts/arms. Not happening.
Now to bolt them up and start rebuilding the rest of the front end.

Jim: Harbor Freight is just a stones throw away. Why not buy a small press and do them yourself? At one time someone had a link to a fantastic DIY replacement of the bushings. I believe the site went down when the owner died. If some one has it it would be a really super addition to the Wiki.

I have it. It featured on buzz@lanset.com. Sadly, several years ago, Buzz passed away and the site which covered all sorts of interesting information closed down.

I managed to recover just about all the "bushings" section and I shared a copy with someone who needed the informotion. That person promised to send me the "missing" picture from Buzz' article, by replicating that particular task. As with many promises of rare information, the recipient either forgot or couldn't be bothered !

I'll happliy share it with anyone who emails me, AS LONG AS the requester, when he/she gets to this task, takes some photos and sends them to me so that I can complete the restoration of Buzz' work to share with others.

This time I will happliy name and shame anyone who promises but doesn't deliver. :D

If you want a copy, email me DIRECTLY at muttguru@aol.com (Don't PM me for a copy)

Kind regards....

I always used a piece of threaded rod and a couple sockets. Worked better then the damn three hundred dollar tool set for doing that job! :roll:

And as always my thanks to all who respond to the questions/issues we put forward here at G838. Since I have already purchased the replacement arms, upper and lower, for the front, I will keep the ideas in mind for that time when I attack the rear suspension.

Time has flown by, and earlier this week I had a break in the heat and a chance to run my new compressor, meaning to remove the ROPS footings so I could gain access to the gas tank. The mid-mount on the left overlaps the rear edge of the tank, holding it prisoner and preventing removal.

In dealing with the bolts, found that some minor channel damage underneath (previous off-roading I suspect) made accessing the bolts/nuts challenging. Well, managed to break the new Craftsman 1/2" impact wrench during this activity, resulting in many bad words. Son-in-law came to rescue with a Husky replacement. Now that all of the footing attachment hardware is out, the next chore is to remove all of the pipe insulation that was overlapped on ALL of the ROPS tubing connections/pins. Sticky, nasty stuff.

Remember the front coils that had been modified by adding more coil by welding? Seems the rear coils were modified, but only by the addition of the coil spacers that fit at the top of the coil and in the spring pocket. These look to be about two inches tall. I'll have to refer to the TM for instructions to access the top of the coils and remove the spacers.

Going to start replacing the brake lines next week, then move ahead with getting the new A-Arms installed. Time to get this project out of the garage!!

With weight on the vehicle take the lower shock bolt out and then jack up the vehicle by way of the differential and the wheel will drop down to the point where the spring will come loose. NOW, with the added spacer I do not know if you will run into clearance issues with u-joints or brake lines but I would definitely take the axle off at the wheel end, and watch the brake line. The line should not be an issue

Thanks Rick. The removal of the rear prop shafts was going to happen anyway, as I am replacing the U-joints all around, and the fronts have been done for a while.

Since the coils were extended (by one means or another), it seems the rear differential was adjusted as well, with the addition of some type of spacers between the diff and the cross-member. I wonder if this was done to mitigate the driveshaft angle change with the extended coils? I'll take a photo of what I have and PM you with it, since the Photobucket issue has left me without a means to post pictures here.

DAMN! I HATE Photobucket!!!!!!!!!!!!!!!!!! Locked up my computer with adds to the point I had to shut down the browser and start over! Those spacers on the rear are an effort to quiet it down. I do not really think it works and on top of that it appears they used a much smaller bolt, or in this case threaded rod to hold it all together.
