Steering wheel vibration poll -- responses appreciated

[e60ral]

45 responses so far and the only thing that really stands out is that the majority of people without steering wheel vibration don't have rock sliders.

i can't imagine what rock sliders would have to do with anything, i have no vibration and rock sliders

it took discount tire 3 or 4 attempts to get my tires balanced, but after that no issues

People have this issue with bone stock vehicles and OEM tire sizes on tight front ends? I've come from a lifted Jeep so I do know a fair bit about front end vibes through the wheel and where they typically originate, I'm sure many of us here do but in the Jeep world at least ( and my good buddy makes his living on modifying them specifically ) they don't just come on all of a sudden or come and go, there is always a common denominator even if its simple tire wear, belt shifts which are really hard to diagnose.

We tossed u-joints and stabilizers at my last truck to try and calm a minor vibe at highway speeds to no avail, turns out a simple decrease in the transfer case drop kit did the trick ( which is usually the opposite problem - you need more )

I know our front ends are significantly more complicated then the front end of a Jeep which has half the alignment consideration too but I have a hard time understanding these issues crop up on bone stock vehicles. I hope - I only have 1500 miles on our TRD OR right now but drive frequently at these suspected speeds and everything rolls along as smooth as butter.

I don't expect these Duellers to last too long, so I'll be very picky on replacements - the Duratracs on my last Jeep started to have vibe issues and required frequent rotations to keep their belts wearing properly I thought. They sure got loud as hell around the 50K mark which was annoying.

solid axle vs ifs, very different situation and very different causes and solutions

It's a pretty large amount of steel that bolts directly into the frame, so maybe it's magnifying an existing resonance mode. I'm trying to keep an open mind in looking at the results.

It's the only result where there's a significant difference between people who answered yes or no to Question #1 (having steering wheel vibration):

I do have the sliders now but my steering used to vibrate even before I installed the sliders so I answered No to sliders

Road Force Balancing

I had vibration issues ever since I put on my BFG KO2's - even after several alignments and tire balancing. It was so annoying and thought about going back to stock tires for a while -- until I read another thread about Road Force Balancing.

Ever since I had Road Force Balancing done, the ride has been smooth as butter!

Also, the person they put to do the Road Force Balancing is a more tenured and experienced employee...not just anyone they have changing out tires.

I have the 275 KO2's as well and I will be doing a road force balance soon.

I've had them road force balanced, but the vibration magnitude and speed didn't change at all. Going to try again today.

Filled it out however I do not always have the vibration. Case in point I had experienced some vibration around 4k miles and I noticed it going on for a few weeks at slower highway speeds but it has not happened recently and I am now at 8k. Most of my driving is on surface roads and occasional highway but I work from home so definitely not a commuter (I average 7700 miles a year).

When I did have the vibration it was in the wheel and not felt in the seat so it was clearly coming from something in the front.

Let's look at it from a 30K ft view. Very few people who have sliders ONLY have sliders and nothing else. Most have bigger wheels and tires, suspension mods, racks, skids, winch or a combination of above. I think it would be a safe conclusion to say more people have vibration problems that have modded tire, wheel, spacer, slider, skid, bumper, etc than those that left their vehicle completely stock.

I don't know of anyone who just put sliders on a stock vehicle without changing something else too.

this is a great example of being misled by statistics, and why understanding different methods of multivariate regression and analysis is important. engineering curriculums need more statistics.

Done. No vibration ever for me at about 30K miles.
My 4runner's an all stock 2012 limited, but with a set of wheel and tires from a 2013 trail. It was cheaper in the long run to buy the 17" rims/tires than replace 20" tires.

Had it. Slept through it. Too many other classes that were more important at the time. With that said, I use a lot of the concepts now in my daily job.

Hi there. Now you do! lol :dancin::fro:

Bone stock other than sliders here as well.

To be clear, I haven't come to any conclusions. I'm merely pointing out that the only thing that stands out from the survey results is the existence (or lack) of rock sliders.

The parts I design in my line of work are manufactured on the scale of tens to hundreds of millions and I have over half a billion parts in the field. Please don't lecture me on statistics.

 

[KEWW Pro]

Between 54 and 59 mph anywhere my vibration occurs 100% of the time.

My curve ball as follows...

17 TRDP

0-400 miles, stock
400-700 miles, +Spidertrax 1.25" wheel spacers
700-present (1000), +Cornfed 2/1.75 suspension lift

Vibration from day one through present day.

It does not bother me too much as if I hit 54 in a 35...er...45 it lets me know I am going too fast and if I drop to 59 on the highway I need to wake up! Haha

Good survey though, glad to know it's not just me.

you assumed a relationship between 2 variables despite other variables existing without other analysis, that's a no-no

 

[e60ral]

could it be the needle bearing? we already know a lot have issues with needle bearings, could vibrations be related?

 

[engineeer]

I didn't assume anything. I merely pointed out the only thing that stood out from the survey results. Here are my words again:

At no point did I say I believe rock sliders are the reason for the vibration (I did venture a guess at how their existence could contribute to the vibration in response to your post asking how they could), which is the only way to see me implying a relationship between two variables. Putting words in someone's mouth is a no-no.

it's okay bruh, statistics be hard
