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

Comparing a w900 or 389 to a cascadia is apples to oranges. What about international prostars? Or the volvo? FL cant be that much cheaper.

 

I guess i got the cream of the crop freightliner

 

have driven a t600 brand new had a vibration would eat the right side steers for lunch. Now im in a brand new t660 same problem right steers are junk i have done a 3 axle shocks braks drums front alignment and new steers . Nothing has worked

 

Yes... I suppose it's common issue of super-singles... I have 100 000 ml on brand new Prostar. Tires were changed 3 times by now... After 3rd time we've taken one of tires (the worse) on balancing machine - it called for 24 oz weigh... Ridiculous... So they bought one more new tire, that makes 13 all together since new... Still shakes, not as much as original ( it was really bad) but still shakes, especially bob-tailing or with empty or light load trailer.

 

pay the money to have your tires balanced on the hub it is usually caused by a unbalanced brake drum

 

Have same problem . Just replace center hanger bearing on cascadia . Ride smooth again. Check for play in bearing

 

Check ride height. A chew can os close to most specs it should fit above the spring. Most of those trucks are 2 5/8 to 7/8. Also do you feel it in the wheel or you seat more. Another issue lately is the drums not round. Another sign of tires is if you can drive out of it.... if you want to check pins or bearings in front. Jack up the wheel and push on top. If it feels like a clunck then one or other is bad.
