Erratic steering

Hi.
I have a 2013 Wrangler Unlimited that is 100 stock other than a bit taller tires. I bought it from a friend with 8k miles and he adviced me that at highway speeds the Jeep would want to go left or right with little or no input to the steering wheel. Kind of light feel to steering. He changed most of the suspension components and still the jeep handled kind of odd.
Any idea on what could the problem be?
Thank you very much.

You say it's stock but changed most of the suspension components. What was replaced ?
Was the jeep ever aligned ?

100% stock, with most of the suspension components changed, at 8,000 miles, 2013, doesn't make any sense.......

How much psi are you running in the tires? What size tires are you running? What suspension components were changed? Have you checked the tires for bad balance?

(something about those funny washers used to adjust the lower control arms comes to mind... the lower control arms may need to be pushed out a bit...angles... ) ...but best advice is to have a front end alignment done as it should confirm the proper angles for the steering and suspension components. Another question, is why replace the suspension at 8000? Accident damage?

Sorry for the misleading info. The previous owner changed most of the components for new original ones. He thought maybe one could be bad so he decided to spend money replacing them with new OEM parts to see if that could correct the problem.
Thanks everyone!

Today I will take the Jeep for a toe and camber check. According to my friend he did that sever times and it did not solve the problem. I am kind of suspicious on what settings it has so I will go check them. I suppose a bit of toe in is suggested? What about Caster?

Toe = about .09 - .12 (in) stock
Caster = 3.7 to 4.7 (not adjustable)
Camber = - .6 to .10 (not adjustable)

If he is stock he doesn't have to worry about caster angle, you are talking about cam bolts used to increase caster after a lift

I would still check the psi in your tires. If they have too much air in them it will cause the jeep to wander on the highway. Just my .02 cents.

[QUOTE100% stock, with most of the suspension components changed, at 8,000 miles, 2013, doesn't make any sense....... ][/QUOTE]

Could be so many different things it's tough to give advice without more detail and the history of this Jeep.


so, tell us more about your Jeep.

You say it's bone stock with oversized tires.

Has it ever been in a wreck? Possibly before your buddy bought it. Carfax it?
Why did dealership replace most of the steering components? What do the repair records say? Why aren't they trying to fix it for you now?

If the dealer didn't do the work why on gods green earth would your buddy spend all that time and money on something the drivetrain warranty covers?
What brand, size, load rating and pressure are those oversized tires?
Wheels are stock, what size? Wheel spacers?
Why did he sell the Jeep to you instead of trading it in?

Not to question your buddy's honesty but something doesn't add up with all this front end work at 8K miles and his comment on it just randomly swerving right or left.

So with a 4" lift is .12 degrees of TOTAL toe acceptable? .06 on each side?

its tire size that determines toe spec.
.12 to .16 is perfect for a 35" + tire

The description of the problem sounds like a very low degree of caster.... or a very sloppy steering box.....

While your at it. Would you happen to know the toe specs for 285/70/17's kjeeper10? I replaced my stock 16's and am curious how off my toe is.

You should be ok with the stock spec. .17-.23
but I would go (.15-.17 total)
