Front Tire Lean in reverse

[coachtmc]

I recently bought a 4 inch lift kit from Rough Country and installed it on my full size 89 Bronco. The installation went well, but the front tires lean in drastically when backing up. When I drive forward they go back into a normal position. Any help would be greatly appreciated.

I had put a 2.5 inch rough county lift on my bronco an mine does the exact same thing. and some of the other guys on here will tell you that theres do the same. so i believe it is the nature of the beast. but if any one out there does know anything about it and how to fix the problem i would like to know also.

I put a 4" Superlift on mine and have had (2) front end alingments done on her and it still does it too. They told me when you start fooling around with lift kits you can never get the camber and caster perfect. Looks like were gonna have to live with it.

thats not totally true. I replaced some front end steering components on my truck and did an at home alignment until i got it right. Just before i got new tires i had a shop align the truck and now i have the same problem you guys are talking about on stock suspension stock size tires.

the problem is the toe in. The shops you took the vehicle too have too much toe in. This means if you were to draw a line forward from each tire they would eventually meet. If anyone of you ski think about snow plowing with your skis. when you drive forward with too much toe in your wearing the outside of your tires. when you back up you are making the tires want to toe in more because of the friction. because of the suspension characteristics it allows your tires to gain negative camber.

This weekend im going to adjust my toe in on my truck until it doesnt do this anymore.

Toe in makes your truck want to track straight and helps create stability.

Toe out makes the truck wander and is very unstable at high speed.

Friction naturally makes the tires want to go toe in. A good adjustment is about 1/4degree of toe in. The shop i took my truck to said he could only get it within a degree which is bull.

This also puts unneeded wear on ball joints when backing into a parking spot.

Eastwood sells an alignment tool for around $50 that you use at home. you can probably get your alignment better then most shops(that dont use lasers) because you are more concerned with it.

Basically when i adjust it i make small adjustments at a time, drive forward park look at the tires, drive backwards, park look at the tires and go from there.

to me that sounds like the shop is not willing to work with it. If you use proper lift kits that relocate the TTB arms and the radius arm there should be little to no change in Caster or camber. A 1-2" lift is more difficult to get the Caster back inline because its done soley with a bushing on the top of the spindle but it is still possible. What this does change however is the camber gain because of the angle your TTB arms are at and the location they are in the travel arc. I would need to make a few drawings to explain this better.

all of mine did it and my tires wore fine and they straightened up when you started moving forward

Its just the nature of the beast. in stock form they do it it just gets more obvious when you lift it.

Hey im new on here but this is just my imput on the subject.

I bought some 33" BFG A/T's and never looked back, then got the truck aligned and was smooth sailing except for the occasional tire rub. <_<

I recently added a 2" lift to the front end of my bronco with some Dysart Coil Spacers. The lift went in with out a problem, and i threw in some RS5000 to support the ol' girl and it rides slicker than snot on a door ****. And plus i eliminated the tire clearance issue i had with hard turns. /

I had the truck Realigned after putting in the lift because i screwed up the angle of how the tires sat, it looked like this \ /....... needless to say they were leaning. after the realignment the tires sit perfect and rolls straight down the road.

aside from all of that in any gear R or D, 4x4 or not the tires sit normal. But if you guys say an alignment isnt helping then i say just live with what ya got no harm no fowl in most cases, however, there is the few with bad tirer wear.

best of luck i guess
