I was towing my boat this weekend and my truck had a really bad shake going 55 mph at 1500 rpms. When I went 55mph at higher rmps it didn't shake though. Maybe I just need a new truck! What do you think the problem could be.

could be U joints or front suspention problems like tie rods or unballanced tire

Was the shake like a wash board shudder you felt in floor boards, or was it the whole truck shaking?

Does it do it when you are not pulling trailer?

When was the last time you had the trans flushed?

The shake is happening when not towing my boat too, just not as severe. The truck shakes and the steering wheel really shakes. I had an allinment not too lang ago and my front end is less than a year old. I am probably due for a tranny flush. I guess I am hoping that it is the tires since they need replacing and I will be getting new ones very soon. 17" rims are expensive for tires though.

By what you just said, I would suspect tires then. The shop you have the tires replaced at will inspect the front end most likely also.

I thought at first of a possible trans/torque converter shudder, but now to me it now sounds like tires. Always a good idea to get the trans flushed if it is over due.

Good luck!

With the shake changing with rpm and not speed I would say engine miss or trany. 1500rpm you should be in overdrive which means if it is an engine missit would really shake.

Are you due for a tune up? You may have a coil breaking down.

What engine? What mileage?

If it is a load shake, rather then a speed shake then most likely a missfire. When it is shaking take it out of OD and see if it still shakes, if it does then you most likely have a tire concern. If it goes away then it is either a enging miss or a trans concern, most likely engine miss. The 5.4 engines were comon for bad coil packs, and the 4.6 were comon for plug wires.

Yep, I did forget about the C.O.P. miss fire shake.

Does the check eng. light come on at all?

I still stand behind tires though, after he said the above.

You never know? grin

I would like to hear the results off doing this!

Have the same year truck and had the same problem. I got the scanner from the auto parts store and it was the #5 misfiring-new coil pack and she was good to go.

    • I have a little can of lock deicer taped to the gas tank under my tank cover. I haven't had to use it for the lock, but did use it the other weekend when the latch froze up.
    • Because they didn't need to. President Obama was totally open to the press corps and never threatened to "throw them out of the White House". President Obama never refused to take a question from a legitimate and credentialed reporter and told the reporter he represents "fake news". And of course President Obama would never think of ridiculing a reporter who suffered a serious physical problem. We are moving from an erudite, articulate and thoughtful man,  sensitive to others, to an inarticulate baboon who cannot put more than 140 words together at one time. The Donald is going to destroy the Republican Party.   Remember I said this and on this date. I won't need to say it again.
    • we dont remember asking you!!!!!!!!
    • Have to admit, I was expecting a different conversation based on the subject line of this thread!   Would it work to have a hole in 3 corners, with the guys grouped toward the center  with their backs to each other? Assuming your hub has 2 doors, that would allow people to get in/out without too much hassle.   I'm also assuming if you're currently fitting three people in a three person hub, you're keeping things rather scaled down. I have a three-man, but once I get chairs, a heater, minnow bucket, etc. in there it's really a 2-man.  
    • Well Walleyehooker, you may be in luck, because after 5 days of this warm weather it may take a week or two of cold and snow to just get back to point zero on the trails anyway! So you maybe back by then.
    • A 26 incher from a couple weeks ago.  Fattie too.
    • Great pics!  Thanks for the update!  I'm headed up this weekend and hope to get on 'em.  I'll report back next week with my findings.
    • Oh c'mon you guys they all say 60 Db, ya right! You'd have to be nuts to spend double just cause it says Honda or Yamaha on it.
    • Taking fish from our non-sustainable lakes to consume???!?!?!?!!!  *GASP* O MY GOD....  
    • This has worked best for me. I can have better access to the door for all and a good spot for the heater.
