i just bought a 1995 ford bronco with a 6 inch lift and while i was driving home i hit a bump and the front tires wobbled bad..any thoughts on why?

 

There are no fewer than fourteen (14) pivot-points holding the front axle and steering linkage together. Any of these that are worn, damaged or misaligned (6" of lift should have had alignment shims replaced and axle pivot points lowered) could be the culprit. Beyond that there are the tires themselves, wheel bearings and shocks. Do a search for this condition in the forum... you will get a lot of information back.

 

I will tell you my experience on the problem i fixed for a friend only it was a dodge with a solid axle As greystreak92 stated you MUST! check (AND KNOW HOW TO PROPERLY!) all BALL JOINTS, RADIUS ROD BUSHINGS, TRACK BAR, AND ALL STEERING PIVOT ENDS,WHEEL BEARING PLAY, TIRE CONDITION, SHOCKS, .
And in my case It turned out that only thing I found bad was the track bar on the end that pivots in multiple directions (THAT LOOKS MUCH LIKE A TIE ROD END) and THE STOCK REPLACEMENT not the cheapest part either. KNOWING THAT HE DOES LOTS OF PLOWING AND OFF ROADING OCCASIONALLY. I found him heavy duty & rebuildable and adjustable aftermarket one. Put it on and still had the issue but less often. I felt bad & kinda stupid to after having him purchase 300.00 bad *** track bar. [Even though needed it] Double checked everything again and all was perfect. thought about it for some time and decided to take the steering stabilizer off and check it by hand mounted. In a vice AND BINGO ! IT WAS BAD 25 DOLLARS LATER NEW STABILIZER ON THE TRUCK PERFECTLY SMOOTH RIDE ! So make sure to check your stabilizer by hand mounted in a vice. and if every thing is ok on your steering and suspension WITHOUT A SHADOW OF A DOUBT! and your truck is not equipped with a steering stabilizer GET ONE AND GOOD LUCK !

 

Lots of caps... Anyways, I am not so sure on the Trac bar for a TTB front end (GS92 clarify?) but I don't think they are pivoting like a tie rod end.

My bronco is a 78 with a D44 straight axle so of course it might be different BUT, this is what the Trac bar looks like.




It pivots up and down. My axle side bushing was gone so I had a death wobble. I replace the bushing, then found out my tires were Cupping, after those were replace it was fine. I'd also recommend checking the Steering Stabilizer.

One easy test is to slid under the front and have someone climb in the truck, unlock the steering (engine off), and turn the wheel back and forth a little. This way you can get a good view of the steering parts in action and you might be able to see where the slack is. If you don't see anything that stands out, the next test is to jack the front up and wiggle stuff. Grab the wheels and shake the crap out of them, get a hand on the top and bottom and wiggle them like you are trying to take them off, if they move your ball joints may be worn.

There are a lot of people who have been in the same boat as you, the search function for the forum should help out a lot.

 

There is no track bar in a TTB front axle. The axle is articulated and each half is attached to the frame rail opposite the wheel it holds. So, the driver's half of the axle mounts to a bracket on the passenger side frame rail and vice-versa. So, basically, any information about fixing track bar problems is a moot point when talking about TTB axles.

The axle pivot bushings in TTB axles are the wear-points that will allow the axle halves to shift from left-to-right under the truck during steering maneuvers and off-camber situations if they are too badly worn.

Too often I hear the (terribly misguided) recommendation to "add a steering stabilizer". DON'T! It may make it "feel" like the bump-steer has diminished and that your front end is "all better" and NOTHING could be further from the truth. The hydraulic impedance/buffer created by adding a stabilizer ONLY serves to mask those issues that will cause greater risk and lead to greater damage to steering and suspension components if you can't "feel" them getting worse. A stabilizer HIDES steering feedback through the wheel that allows the driver to know when things are beginning to get sloppy and worn. TTB-equipped trucks were not factory-equipped with stabilizers for this reason.

 

I guess you learn something new every day . I have yet to fully understand the TTB setup. Maybe one day.

 

Im sorry to not clarify I was speaking of a 3/4 dodge I was working on and it comes stock with a steering stabilizer on it. so steering stabilizers have there place and any more than one stabilizer is nothing but for show. my point is was MOST IMPORTANTLY "PROPERLY" CHECK ALL WEAR POINTS AS YOU STATED GREAYSTREAK92 there are 14 SOMTHING POINTS FOR THE FORD AS I have 3 twin beam IFS trucks not one has a steering stabilizer but because of the looseness that occurs in an older truck steering box & steering shaft joints ect, it may possibly help this? All i was doing was relating a situation where another truck that had nothing physically wrong but a little wear. And a bad 25/dollar factory instaled stabilizer fixed it. I was trying to help and did not mean to rattle your cage mr greaystreak92 sir I apologize if this is how you feel.
