Turns out the only thing i fixed doing this was about maybe 1/2 the slack i had in the steering. The shimmying is still really bad when i hit about 35-40. I'm glad i have a new part cause the old one was in bad shape but I am disappointed that this didn't help the main problem. You guys mentioned that the u-joints may be a cause of the shaking in the rear driveline. I know the front driveline wouldn't cause it cause it isn't spinning.You guys also mentioned something about the tranny and torque converter causing it, and i have been having problems with my tranny not shifting properly. It slams hard when i shift to reverse and i heard that can hurt the joints. I am at a loss and figured it had to do with the front end but when it shakes you can feel it down your entire body too.

Well at least you fixed something and eliminated a suspect. Hey im a little worried that with both of posting are problems on this thread that members may be confusing our symptoms and hindering both of us from comming up with a solution. Our symptoms are similar but more than likely we have different problems. I dont know if its possible to go back and change the color of the text for all your posts(since you have less posts and it would be easier) but maybe thats one way to do it. I don't know maybe just by me posting this someone who reads the thread for the first time will be careful to read our posts separetly. Just lettin you know how I feel about it. Until I install my new parts I will mainly just be responding anyway. Shipping was delayed until the 7th! errrr
Ya i gotcha, I can go through and change the colors a bit. I have been thinking about it and am wondering if it actually is the drive line, I have burned a bit of rubber and the sudden torque may have bent or twisted it somehow
hello long time reader. new member. my 96 also started having a crazy shake in the steering as well. rotated tires but still shakes... not all the time but every once and a while?
Thanks for the the tips and sorry to hear about your truck. I actually have suspected that its in the driveline and it causes the whole truck to shake. I don't feel in in the steering the way you would usually feel a steering or front suspension problem. From inside the truck I feel it most on the floor above the trans. All the parts im replacing are actually coming from necessity to pass safety inspection. After im done with that I figured it would help others help me diagnose the issue by eliminating those things as an issue. On some other forums I read about similar issues that ended up being the cv joints. After im done with installing my new parts I will do what you recommended. Thanks again I really think your right about this.
Also I didn't pay much for the Bronco and Im only just now approaching what its actually worth after spending about 1300 including tires. Well I guess that depends on the trans/ transfer case...
Thanks and don't worry, the truck that had that problem is long gone, since around 1990. I never figured it out, but seeing how many new parts I put on it there wasn't much left to consider but the transmission somehow. Mine would always shimmy right around 35mph. It didn't shimmy at any other speed. I wish you good luck in finding your answer!
PS - My 1990 Bronco with 150K rides very smoothly, especially considering that I have the heavy duty suspension etc. It ain't no Cadillac, that's for sure, and it can still be a rough ride over bumps etc. But when driving I get no sorts of shimmies at all. People who ride in the Bronco for the first time have always said that it rides smoother than they thought it would. Even though I have oversize tires 32X11.50X15 on stock suspension. I credit a lot of it to the tires. Unless you are doing some serious off-roading, I recommend Michelin tires wholeheartedly. I hate a vehicle that vibrates and I have bought many tires for various vehicles and Michelin comes out on top as the smoothest. I even asked a few tire guys which brand would give me the smoothest highway ride; and tire guys in completely different states all said the same thing. Michelin. I don't use my Bronco for heavy-duty off roading; I just use the 4X4 for trails, or for when there is snow and ice on the ground. So I'll be a Michelin buyer for life.
Well I decided to do some work on my 78 and it turned out to not fix really anything i ment to fix. This is what i got,
And my old one,
Old next to new,
Some of the bushings are a bit worn, top one is new,
And the finished product. Did you guys know that stickers not only add 5 horsepower but they also add 2 more inches to your turning radius
I too have the tie rod stabilizer. It had one since I got it so I cannot compare it with stock. Although I did put in a new one when I was doing the other six shocks. Perhaps a tie rod stabilizer could help him, but seeing that he doesn't feel the vibration in the steering wheel I don't think a stabilizer would help him. It's worth a shot though, they're not expensive and are easy to install. I can tell you this much - I'm not sure if it's the stabilizer, but my Bronco drives very straight and I've been able to take my hands off of the wheel for several minutes at a time just to see what it would do and it kept on going straight all by itself for along time!

Ya it didn't really help me, it summed up a bit of slack but the shimmy was still there and getting worse. Turns out i needed new tires, mine were separating within themselves so it was creating bubbles and stuff under the tread. I got these:
And they made a world of difference. I no longer have to fight the steering from going right and there is no shimmy, there is slight vibrations but that is mostly tire tread and the crappy roads i drive on
Ya i had a few people talking to me about it, I stopped at Discount Tire and they told me the same thing so i decided "What the heck, I need new tires anyways so it can't hurt" And it made a bigger difference than i thought
Had a problem with a tire patch on my 4x4 S10 Blazer that caused a bubble in the tire, and then on the one opposite on the rear, that little truck looked like a tugboat being tossed about it shook so much.
