This is the original motor with 181000 miles. Most of the time a vehicle shakes because of three specific items.
Removing one drive shaft will relieve the bind restoring normal driving.

The angle of the pinion nose should be within a couple of degrees of the angle from the transmission slip yoke so that they cancel one another out. The pinion angle changes slighlty as the diff winds so I reckon your decel vibration is probably because the angles are slightly out. The vibration does not come though the brake peddle or gear shifter.
Oh its a 5 speed. I really didnt notice the vibration till I changed tired went from Michelin Pilots to Kumho ASX. I have had the new tired balanced twice.
The vibration seems to. One of the most common cause of driveline vibration are worn U-joints or slip splines out-of-balance components yokes out of phase or misaligned angles approaching critical speed range and yoke ears that are not concentric with the splines. If the VC is locked it is the same as driving with the CDL locked.
This will bind the drive train causing stress on all drive train components. Will change the angle of axles etc any small looseness in parts will be magnified into a bigger vibration. Removing one drive shaft will relieve the bind restoring normal driving.
So they basically just disconnected the 2 shaft parts and aligned them properly and pre-loaded the CSB. And the vibration is now gone thumbup. There was a part that showed wear bad condition.
Im not sure if it played any role in the vibration but they replaced it. Here is the part. I think its labeled E in the picture.
Vibration during deceleration. A friend with a 2003 road king is experincing severe vibration during deceleration from any speed. Everything seems normal during aceleration through every gear.
Replaced the front motor mount no difference. All the vibration seems to be right under the seat no abnormal shaking in front end or handlebars. This is the original motor with 181000 miles.
It runs great but I get the annoying vibration when the car decelerates. I dont get it all the time it mainly happens in 3rd between 2700-3000 rpm and on freeway speed when I have to let off the gas. It feels like it either coming from the tranny or a brake is dragging.
I have read in a couple of car blogs online that in general a faulty inner CV joint can cause front end vibration under deceleration and both inner CV joints are leaking one badly as I mentioned. It goes to the mechanic tomorrow to make sure it isnt something simple. Worn slip yoke splines.
Steady vibration that increases with speed Cause. Worn U-joint or out-of-balance driveshaft. Cyclic vibration that varies in intensity.
Intensity increases at a specific speed range worsens during deceleration Cause. Pinion angle too low not parallel with front yoke on driveshaft. Sometimes its a shudder other times a shake from your engine.
When you experience such vibrations it may be a sign that your engine is deficient of either air spark or fuel. Your engine needs these to run smoothly. Signs to look out for when your engine shakes.
Your car jerk when you accelerate. Im guessing that if youre decelerating from 60-65 and you push in the clutch to basically kill the RPMs then the vibration goes away. One other thought though or question.
If the driveshaft was the culprit my guess is that whatever RPM youre at during 60-65 mph the problem would present itself at other speeds doing the same RPM. 2006 DC SR5 TRD 4x2. I have been experiencing a vibration when I initially begin to accelerate from a stop that goes away but then returns around 50 mph up to 80mph.
It also vibrate during deceleration at those same speeds. What causes vibration when decelerating. Most of the time a vehicle shakes because of three specific items.
Problems with the tires or wheels loose or broken suspension components wheel bearings that are worn out. What causes vibration when decelerating. Most of the time a vehicle shakes because of three specific items.
Problems with the tires or wheels loose or broken suspension components wheel bearings that are worn out. That causes more load to those suspension components and can cause the shaking youre describing at the speeds youre indicating. If you spot adhesive residue in an area that looks to have been a position for one or more wheel weights then this might be the cause of your vibration.
Bent wheel or damaged tire Americas many pothole-riddled roads are a very likely cause for driving vibrations. Cupped tire most likely means the tire has been run with low air. Check the pressure in both tires and see if it helps.
If the tires are cupped bad enough. Momentum is doing most of the work. When accelerating and decelerating however theres enough load on the driveshaft and joints to cause vibrations that will increase and decrease with vehicle speed.
It will be most pronounced when first stepping on the throttle hard and when the brakes are firmly applied. Lots of other things can cause this. I had the problem bad and it went away 90 with a drive shaft balancing.
If it is it will vibrate when decelerating. I had that problem in my 71 Camaro several years ago. Its an easy thing to check.
If you dont want to remove the tranny get some 8 bolts same. Most of the time a vehicle shakes because of three specific items. Problems with the tires or wheels loose or broken suspension components wheel bearings that are worn out.
With a four wheel drive Jeep Grand Cherokee the first thing Id dive into would be CV joints being extremely worn out or the tie rod end joints. If the vibration steadily increases with driveshaft speed either accelerating or decelerating the symptom is primarily the result of a driveshaft imbalance or yoke run-out. Sometimes this yoke run-out problem can be improved by rotating the U-joint 180-degrees in the rear end differential yoke.
A howling differential is one of the worst sounds any car guy or girl can hear. And once youve heard a clunk howl whine or vibration youll want to diagnose it. Its possible that the sounds youre hearing are not differential-related.
They could be caused by other driveline or axle components. This quick guide will.
