I have a 2000 Winibago E-450. I have a bad viberation at 40MPH. It has new tires front and rear. It does not feel like the front, I don't feel it in the steering wheel. Faster then 45MPH it seems to go away. Any ideas what to do?

Check the u-joints and carrier bearing.

^X2. Center carrier bearing usually fails before U-joints, unless those have never been greased.

Did they have ODB ports in 2000 ?If the above doesn't pan out, have somebody plug in and check for codes.Might be a misfire condition in the engine (long shot).OH.....and if you haven't had the wheels "re-torqued" since the tires were put on you should do that....NOW.

Did you just get this coach and notice the problem, or have you had it awhile and now the problem has developed?U-Joints work well, only when they're pretty close to straight-on. When they have to accommodate quite a bit of angle, they accelerate and then slow the shaft. That's why modern FWD and 4WD vehicles use CV (CONSTANT Velocity) joints instead of U-Joints. Point of this is, you need a little "off angle" for the driveshaft to NOT oscillate as if it was one long shaft. But not too much. I helped a member here with some angle measurements, and it turned out the front flange on the differential was too vertical. Rear axle needed to be shimmed so the flange came closer to the angle of the driveshaft.All said, the Carrier Bearing(s) are big ball bearings that can go bad, but often the rubber mounting breaks down, and you get vibration.

That's what I did. Mark every match point by spray painting it. Then you can reinstall it like you found it.

Hi I am new to this forum but I just got finished fixing my 31' BT Cruiser E450 vibration problem at 45mph. I did some checks directed by my local driveline repair shop.Any one area can cause it. Jack stands under rear axle and ran to 45, nope. Removed axle shafts run to 45,still vibrates, remove rear drive shaft, no luck,center drive shaft, no luck, front shaft remove, no vibration.Sent 3 drivelines to repair shop. Common problem when frame is extened the front shaft is lengthened poorly. Also checked joints and center brgs. all good.

Probably the drive shaft but I once had that problem with a station wagon. It turned out to be an out of round tire. When they took it off to rebalance and was unable to they checked the rest of the tires on the car and found only one tire that was not out of round. Goodyear replaced all the tires encluding the spare.
