Check your rear end and make sure it has plenty of gear oil..if full then there is friction in it somewhere and it is probly getting ready to go out.

Vibrating steering wheel & pedals


I would replace ALL motor & transxale mounts if they are
over 8 years old
I would suspect, as usual, the shops don't remove rust or lube
a thing on brakes,I would do that Take them apart again
Recheck all work that was done
I would drag the brake while on the gas, when it
vibrates, to turn off the trans torque converter clutch
& see if that is an issue.
Could have a bad axle joint
I would in no way trust any shop to have done
a though job of what your saying.
You most likely have worn inner ties rod joints on the
steering rack,something else to check
What about tie rod ends & ball joints & upper strut bearings?

Noise in rear end


Provided that this is a rear-wheel drive vehicle, there are a number of things which can make noise when you accelerate. Most are due to excess clearance in moving parts. This means some parts are worn out.

On the outside, the U-joint next to the rear differential can be worn and make noise. Inside the differential, usually a pinion bearing(carrier bearing) can make a noise like a whine or growl depending on the gap.

Now in the axle tube, the axle shafts have a bearing on each wheel. Like any bearing, when they wear out, noise usually indicates failure.

When Torque is applied on acceleration, the parts shift creating noise. If you have a Limited Slip Differential, there are clutch plates which have a material which can wear out. These types of rear ends also need a special Additive to make the parts work. Sometimes you get a clatter when the additive is low.

Have the U-joint checked first as it is the only external part to check. The rest will need disassembly.

Please rate my info.

Severe whining in the rear end. I have had all bearings replaced. some wear was noted on the rear passenger side axle. extended bearing was used as a replacement so it would not be in contact with scored...


The bearings usually make a kind of rumbling sound, whining usually is gears that are not set up right. They would have to have your differential out in order to replace all of the bearings, if that is the case you need to get it back to whoever did the work and have them make it right. You should get it back to them before any major damage occurs.

Trans clunking when slowing down


Sounds like youi may have a few serious problems going on to have that kind of back lash occuring at higher speeds. I have experiance with low spped clunks on Bronkos and your type of vech being a car dealer. One you might try for low speed clunk on take off and braking at stop likts just completeing a stop? Pull the drive shaft and lubricate the splin - two check your leaf springs for weakness and wore bushings - take a look at your shocks - three u bolts holding springs to rear axle housing may be letting the axle housing actually dip or tweak or all those thing in combination - now you may have some serious slop in the pig - transfer case may be causing that clunk - as far as high spped clunk and activity you have a serous problem and you just might drop the transferr case have an accident fliping over..............Mike South Bend Indiana don't just keep driving and making problem worst...........
