Cascadia 2008 vibration-bouncing issue (cant sleep on the road!!)

**Emilie6566** · 09.08.2012

Hi, there's a major vibrstion going on in my truck when on highway faster than 60mph. Freightliner cascadia 2008. Try to balance tire, alligne all wheels, check suspension valve a d driveshaft joint , even flip super single tire on drive... Still vibrating-bouncing a lot, hard to sleep when co-driver drive on highway. Vibration look like its comming and going from front to back... Or side to side, not sure ... Clues?

Have you checked the engine mountings?

I have a 2009 Cascadia, and I have similar problems, although sometime the ride is as smooth as glass. The passenger side cabinet stacks shakes so much I think its going to come down, I too have done the wheel balance and 5 axel alingments, please post if you find out the problem.

Thanks and safe miles,

Larry

not being rude....but its cuz y'all have freightliners....sorry but the truth.....drove a NEW one at the beg of the year...same issues....will NEVER drive one again...quit a company making .42 a mile because we COULDNT sleep with all the rattle and noise etc....

Try getting a new mattress, will absorb the bouncing impact, worked for us in kw

The older Freightliners aren't bad...

check kingpins....then move on to the u joints. any irregular tire wear? when u stop to fuel, touch all the axle shaft faces (the ones bolted in at your lugnuts), is one warmer than the others? (wheel bearing). any slack in your 5th wheel? 5th wheel well greased? tire out of round? mismounted? there are so many things that it could be, elliminate them one by one and you'lll find it

How are they still in business if all they do is shake? Im sure some models of trucks are just as cheap as a FL.

thats a good question...LOL, they are inexpensive trucks...thats how....do a price comparison on a new ftlnr versus a new W900L KW....or a 389 Pete....see what you come up with..havent priced lately but would guess about a $50.000 difference....they are ok trucks to run solo in i guess...but for a team..NO WAY...been there, done that...
