alright i replaced a idler arm an outer tie rod upper and lowere ball joints on both sides and my truck was way out of align now when i go about 40 mph the truck feels like it shakes a little more than is suppose to its not unbearable i just want to know if something is up any body got any advice or am i just being parranoid ?

 

Something to look at could be a possible wheel weight

 

even if it only does it at one speed

 

Yes, it is possible. An out-of-balance wheel will usually have a certain speed or range where it becomes most obvious.

Although, I would probably look to the alignment being an issue. Did you have the truck aligned after you did the front suspension work? If so, I would take it back to the shop and ask them to check it out to see if they did the alignment properly.

 

would a U-joint cause it to shake at that speed? Never had to deal with a bad u joint, but from what ive read on here it seems like u joints act funny like that too

 

If the vibration is in the steering wheel, then I would not suspect the drive train. If the vibration is in your butt, then perhaps something under the truck is the cause. I don't think a bad u-joint would cause any significant vibration, more likely you will hear it than feel it. If you had been 4-wheelin' and a lot of mud was stuck to the drive shaft, you could get a vibration at higher speeds.

 

okay, yea that makes sense
