2008 Volvo shaking

Volvo 780 cab bushings;
I'm not saying this is your problem, just bought both for 110$ and have my mechanic replace both sides; after every 300-400k miles this are gone the cab starts shaking and my coffee flying all over on rough roads even with new shocks and good air ride;

 

Well dealer call me yestefday they said I got couple problem one bad wheel bering second bad tire so when I go pick it up will see what they fix...

 

Thats trucking lol I know the feeling had miss once spent hundreds and it was a 15 dollar sensor

 

Yeah... I thought that I had thrashed a drive line once after getting stuck. Truck was shaking violently afterwards... mechanic knocks the mud from out of the rim... drives fine.
Lesson: make sure that your tires and rims are clean and straight. It apparently makes a HUGE difference.
IDK but I suspect that a good and even set of tread type makes a world of difference.

 

Yeah, if you build up mud or ice on inside of rim, it throws the balance off. Going to shake and vibrate because of it.

 

I was reading this whole post and was just about to tell you that the problem was clearly just a rim, and then you figured it out yourself. Oh well, I am just one of those folks that is gifted with 20/20 hindsight and a quick I told you so gene.

Truthfully, I am glad you got your problem fixed and am thankful for your sharing this experience.

 

Well my vnl670 was doing the same thing. Ended up replacing the spacer blocks on all 4 air spring hangers. $45.00 later and it is working fine. I too spent tons of money trying to figure this out until I had to replace a hanger. Parts were only $11.00 each at Volvo. I will know next time!

 

Gah...this seams to be common with volvos... I have an 09 780 that has the same issues.
So far...
All tires replaced..
All rims replaced.
King pins replaced.
new tires/rims balanced.
Alignment done.
U-joints checked...

Next paycheck, something else will get checked.....I love this truck...but this vibration is driving me NUTS....
