Took truck apart to fix the crack in the steering box bracket.
Inspected the frame, no cracks found.
Cleaned & inspected box bracket, no cracks found.
Drag link ends found to be tight.
Adjusted the box.

What a way to change yer power steering fluid . . . .

 

Finally got it back together.
Drives straight, steering is tighter.
Has what feels like a radial tire belt shake right around 45 mph.
Steering shakes a little, feels like truck shakes side to side around 45 mph.
Does that sound like a tire shake to you guys??

 

Jack you tires up and spin then! If you have a belt separating you will see the tread move side to side, quit noticeably in one spot.
and yes that could cause, that what your filling!

 

OK, tires look good, but I switched them front to rear anyway.
Left front was slighty out of round.
The truck drives smoother, but, on the test drive I got two very violent death wobbles.

Tie rod ends are tight.
New spring eye bushings.
Drag link, steering box & box mounts are tight.
Steering U Joint is tight.
There are no frame cracks.
Leaf spring bolts are all tight.
I guess I better dig into the wheel bearings & such deeper.

I've tried to shake the tires & couldn't detect any looseness.
Is there a special method to checking this??

 

From what i've been told by my inspection guy, ball joint or king pin check is move the tire up and down, with it jacked up of coarse. If you feel play its your joints or king pins. Shaking the tire side ot side is how to check for tie rod ends. Check tie rod ends with a pair of channel lock plires and squeeze the joint and piece its connected to, if this sqeezes together, bad tie rod. I think this is right. Right? Chime in if i'm wrong.

 

A friend has a 91.5 that he spent a fortune on, trying to get rid of a front-end wobble.

Another friend talked him into adding a steering stabilizer/shock-absorber.

It fixed his truck.

Also, check your tire air-pressure.

Low pressure can do all sorts of weird stuff.

 

I drive an old large flat blade screw driver into the curl of the spring , it will open up the hole and then it takes very little effort to drive the old bushings out hope that helps

 

It has a fairly new Rancho steering stabilizer on it already.

 

That is some good advice that I wish I had read many years ago.

Thanks.

 

you may need to buy a shim to take some of the caster out of the front end. it goes between the spring and the axle housing and resembles a small wedge of cheese. had on old cj5 that would go off on the shimmmy shake and it cured it. seems like 3 degrees or so was the least i could change it. i would only do this as a last resort.

 

There's a TSB repair for Ram wheels. Mopar has some special lugnuts that are used to properly center the wheels on the hubs. The symptoms of problems are a shaking and vibration from front end similar to tires out of balance. The specal lugnuts P/N 01273556 with much wider flange area are installed into two opposing lug holes on wheel and all other lugnuts are then loosened. The special lugnuts are then torqued to spec to center wheel and the stock lugnuts are then tightened, and alignment lugs are removed and replace with stock lugs. One set of 2 lugs does any 8 lug wheel. Check TSB's for more info...
