TSB front end vibration

[Jim B]

Hi- I just joined this forum because i just bought a new 2005 ST 4x4 XLT and immed experienced a front end vibration. The selling Dealer checked the usual-wheel bal,driveline, yada yada- Finally replacing the drive shaft w/another oem steel drive shaft was supposed to be the cure-It wasn't! To make a long story short they did a TSB search today. The new TSB and cure is: A new warranteed aluminum driveshaft! I get it installed 10/11.Hope this helps you.. I'll keep you posted...PS this site rocks!

Welcome to the site, Jim. I'm a relatively recent addition to the group here too, and I agree... this site does rock.



Hope all works out well with the vibration.

Wasn't the aluminum driveshaft the original fix for the Trac? Make sure they replace the bolts with new one, per the TSB.

Jim, Welcome to the site, Glad to see another NY'er..



Hope this fixes it, But the drive shaft is normally for the rear vibration, not the front...

You may have a bad tire....Not uncommon..

Get rid of goodyear rt/s.



Install good tires.



Have them balanced until smooth.

Hey Jim, was it the front or rear shaft? My 05 Trac has a driveline hum and vibration at higher speeds. The dealership balanced the rear and it's still there. Do you have a TSB #?

Dave, Its the rear ds. The dealer can look up the TSB-ask them. I don't have the number. They are going to do the aluminum ds install this friday. It will be interesting to see if that solves the steering wheel shake @ 50-85 +mph. I think its also tire related because the same oe Goodyear tires sucked on my previous 4 Explorers. Even if multiple balancing attempts would succeed, they would start shaking/vibrating soon again..I always kept an eye on rim runout-the aluminum rims bend easy on big pot holes etc Curb scrubbing will bend them!.... I don't have any driveline hum[?] ...Great truck otherwise-love it! .BTW I'm getting an average of about 16-17+ mpg w/ an open 4:10,

driving hard/ easy.
