Roaring / Vibration only while accelerating
 

I have a 07 H-3, I did not notice the noise until I had a 2 inch leveling kit installed. when you reach around 55-60 mph it has a vibration and roaring sound that comes and goes. If you let off the gas it goes away. At first it sounds like a typical tire roar, but you can feel it like a wave coming and going. It's one of those sounds thats hard to explain. Thanks for your help.

If its only vibrating under power it could be a u joint.

I checked the skid plates and they were missing a few bolts. I replaced them and it did'nt help. I'll check out the U joints now. Thanks for your help!

I am experiencing the exact same issue. I have no lift installed, just TB's cranked. It is scheduled to go into the shop this week and I'll let you know what I find out.

Im curious what you find out. Im still leaning towards joints, but interested in what the real cause is.

Roaring/Vibration
 

I'm taking it back to the place that installed it Friday and I will let you know if it was the leveling kit. Someone on another forum told me that you should not go over 24inches from the center of the wheel to fender well. Mine is 25 & 1/4 inches. If the lift can be adjusted I will lower it to around 22inches and road test it. Thanks for the reply's

hello
 

hi, Mcarter64. Nice to meet u.:D

Thanks! Nice to meet you too!

Wow... 25 1/4" Thats really high. 22 is probabably a little low if your @ 25 1/4 in the back. You should be fine in the 23.5 to 24 range from fender to center of hub.That will give you that factory rake but with about 2" front and 1 -1/4 rear gained. You can have your shop lower your t-bars or you can do it with a socket and a few minutes.So when you said you did a 2" kit you didn't just do keys. You must have done keys and add a leaf or keys and shackles. Some people on here report thats they are at that height with Zero problems. Others (The majority by far.) say that's WAAAAAY to high. Are you running stock front shocks? If so they are probably completely maxed so make sure you "swerve those pot holes man." Also I would not recommend going over Mazdas, Rocks, Gravel, Sand, Speed Bumps, or making any tight turns. Your driveway is fine as long as you leave it in "P". ;) :D

I am experiencing same sounds but mine would go after the first gear, and this is an off and on kind of thing, especially in the morning after warming it up.

I just ignored it coz after the first gear it goes. What's supposed problem, anybody?
