Hello everyone,
OK...Its been awhile since Ive been on here so I hope this is the right thread to post this. If not please lmk so I can post in the right thread. Ive searched a lot and there are so many solution but I think this one is slightly different
I started to get this excessive front end vibration. In the past I have had a vibration problem I replaced one of the U joints and the problem was solved.
Of course it only happens at 50 mph as speed rises the vibration gets even worse. I checked the front wheels suspensions and control arms and tie rods...etc. I found that the passenger outer tie rod was done for. So I replaced it and same result. shakes like hell when up to speed. when I let off gas still shakes.. truck has 170k I've only replaced one U joint is it possible other U joints are bad? I have went under the truck to rock the shaft and to inspect the U joints and nothing...looks intact to me..
Then lately my truck been having a rough start I mean it starts but kind of stutter before it starts right up when the engine is cold. when its warm it doesn't do that. I just replaced all six spark plugs, old ones look like crap. thinking that it will fix the problem but nope. I do have a Service engine light on, code is I believe P0430. possible bad ignition coil? how do you troubleshoot that?
