Vibration from engine - 04 FX4
Hey guys, just curious on your opinions....
I have been on this forum for a while, usually just checking things weekly and learning more every week. I have an interesting engine problem which started about 2 weeks ago.
My engine now seems to produce quite a bit of vibration. It is more pronounced at start-up but it can still be noticed once warmed up. The truck is a 2004 4WD, manual trans, and has almost 55,000 miles. I have done all the maintance since new and have never really had any problems with the truck at all except for some rear brake drum issues which I was able to fix fairly easily. I have never replaced the spark plugs or wires since the owners manual states 100,000 miles and 60,000 for extreme use. I have only pulled the plugs to inspect them. They looked a little worn, but not too bad.
I was thinking the following.
1.) One or two wires are toast and creating the issue.
2.) Plugs are no longer good.
3.) Loose engine pulley, not sure which one.
4.) Possibly an exhaust leak, although the truck is still quiet.
Let me know where I should start looking....the check engine light has never come on the entire time I have had the truck.
BTW, I just made my last payment on the truck and I want to keep her another 4 years at least!!! She will now start seeing significantly more off highway time.
THANKS IN ADANCE
