I have a noticeable vibration in the steering wheel at around 45/50 MPH. I've recently remounted the tires and balanced them with Equal wheel balancer and had an alignment done. The tires were not rotated at this time. Also, I've installed an OME steering dampener. None of things has corrected the problem.
I don't recall having the vibes prior to rotating the tires about a two months ago. I would have thought if it was a tire balance issue, the Equal would have corrected it.
Any thoughts? |

Kyle,
If my D2 were acting in this manner, I would:
#1 Check Tire Pressures
#2 Check Pan Hard and radial arm bushings.
#3 Visually inspect steering linkages
#4 Inspect Drive shaft for play.
There are many other threads that discuss vibrations. Just utilize "Keyword Search" under the utilities table to the left of this post.

Paul,
The tire pressure is good, same as what I've been running. I'll be putting in the solenoid CDL this weekend, so I'll check out all of your suggestions.
When I checked the archives, it seemed like most people's problems were wheel balance or alignment related, so I thought I'd fish for more opinions.
Semper Fi,

Hey Kyle,
Please post pics of the CDL install. I will be doing this some day.
I mentioned tire pressures because we are human and sometimes can forget to change the pressure after rotating.
Paul out.......... |

Have the tires "load" balanced. This worked for me. |

Mine did that too. I put on a 2" lift and 265/75 16 tires practically the day I bought it so I figured it was just how it was going to be. You hear about the vibes all the time with LRs.
So in April it was time to get the tires balanced, same thing - no change in the vibes.
This month, it was time to do it again. Now the vibes are gone. I don't know why, maybe the first two were bad balances (including the balance when they mounted them).
I also put a steering damper on this month, maybe that helped too. Maybe not.

Kyle, you may have a bent or out-of-round wheel. Anyone esle driven your vehicle that may have hit a curb, etc. without telling you?
When you installed the equal, was it in bags or was it installed through the valve stems? |

I have cupping tires ( can't figure out why they are cupping though ) but, that seems to be giving me a vibe. How your tires looking? |

kyle, check alignment. should be sligthly toe out.
i've had slight toe in, and that gave me the shakes. |

I'm the only one who drives it and I don't recall hitting anything that would have bent the wheel. I just had it aligned and the shop said everything was within spec except for the castor. I'll have to check the exact numbers on the toe-in/out. |

does the shaking stop when you hit the gas and take it above that speed range? |

I remember there were problems with LR steel wheels to be balanced. Point is, the steel wheels are stud mounted and must be balanced with them this way. Most stores put the wheels on with the center hole on the machine. This hole is pressed steel and can cause the wheel to run uneven on the balancing machine.
This counts for the Defender and Series steel rims (the Wolf 6.5" rim might be better). You probably have a Disco with Alloys - I dont thinks that problem affects alloy rims (but just in case .. costs nothing to mention).
could it be a worn driveshaft that transmittes the vibes through the steering linkage ? |

Ho,
Everything is OK up to about 40 MPH and then it's lousy until I get up to about 50 MPH. Do you know the toe in/out numbers for a D2. The printout I received from the tire shop says -0.05 for the left tire and -0.18 for the right ture. I'm tempted to rotate the tires again and see if it goes away. I guess that would tell me if I have a problem with a wheel.
When it rains it pours. Driving home today, the stupid Service Engine Soon light came on.

does the shake happen after you hit a bump? or all the time you go 40 - 50? |

Ho,
Seems like all of the time at those speeds. It's even more noticeable while going around curves.

does it shake and makes the steering feel light? |

No, it actually seems heavy.

damn, then i dont' know. LOL
for me those were the symptoms for toe in.
ok then, how about... vibes the same under acceleration or decceleration? |

Ho,
The vibes are the same under acceleration or decceleration, just in that 40-50 MPH range. That speed must be a sweet (or sour) spot for the bad vibes. What did they call that in physics, natural harmonic frequency or something?
I'll check all the stuff Paul suggested early on and if I don't find anything, I'll rotate the tires. All of that after the solenoid CDL install. Busy weekend ahead. I'll let you know.

Kyle, are you getting any kind of harmonic noise, and are the vibes isolated to the steering wheel, or are you feeling anyting in the seat of your pants?
Reason I ask is awhile back I removed the harmonic balancer from my rear axle because I had installed a new rear driveshaft that eliminated the rotoflex joint. I figured the balancer was there because of the roto. Well, after it was removed, between 60 and 65 I would get a vibration and a bass like harmonic noise. Very annoying. I replaced the balancer and it went away. Just throwing that out there as a long shot. The balancer is the metal donut shaped device bolted to the centersection of your rear axle. |

Greg,
I don't feel it in the seat of the pants, just the wheel. The weird thing is that it doesn't always seem to happen. For example, driving to work I might have vibes at a certain spot on the commute, but the next day, no vibes.
It's very frustating trying to diagnose.

I had to remove the front drive shaft over the weekend to do the solenoid CDL install. I noticed the shaft was missing some of the balancing plates that are mounted to the shaft. I think this might be the cause of my vibrations.
The truck is going to the dealer this week to fix Service Engine Soon problem. I'll have them take a look then. |

I posted probably 15 question on vibes, and thought I tried every possible fix. A nail in a tire (sidewall) caused me to have to replace the wrangler hp 255/65/r16 with 15,000. New tire 50% less vibe so this w/e I replaced the other. Vibe was worse on that one wheel so the tire shop checked the rim...slightly out of round. My vibes had two causes. 1) A bad tire, 2)a bad rim. The tire on the out-of-round rim had sm evidence of cupping...which makes sense, it was not rotating smoothly and in a 5K lb truck that will cup a tire. Good luck. I lived with that 35-50mph vibe for almost a year before I finally got it 100% corrected. I also had several bad tire balances as well. Weights must be both on the inside & out side of the rim to balance correclty. BTW....never hit anything with the rim |
