Squeak in reverse..

After I lubed my drivetrain I have been getting some squeaking when I pull out of parking spaces. Just recently the squeak, which sounds like someone jumping on an old mattress, has started when I drive as well as back up but not as loud... The noise seems to be coming from the rear drive shaft/propeller shaft. Aft of the center bearing...

Any ideas? U-joint? Center/hanger bearing?

 

I just noticed my truck started doing this too!

 

Leaf springs? Mine squeaks allllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll the time.

 

It's not leaf springs, it only happens when in gear

 

have you greased your u joints in your driveshaft?

 

In gear and not moving? Or squeaks while actually reversing?

 

I have greased them. The squeaking started after but it had been probably too long since the were greased last. Old grease did come out, so not dry.. Happens when I back out of a parking space.. In gear, moving

 

Brake pad wear indicator? I've had customer's vehicles only squeal when backing up, just a thought.

 

Probably u-joints. That's what mine did when they were shot.

 

U joint(s)

 

Defiantly not the brakes. I do know that sound, and my brakes have all been done recently.

How would I know which u-joint? Haven't noticed any play/clunking when moving the drive shaft by hand...

 

They dont always "clunk" at first, usually the first sign is a sqeaking, its the needle bearings chewing on one another the clunk is when they're coming apart

 

Mine did that and it was the U-joints.

 

So when ordering parts, are the Toyota u-joints superior over Moog, ACDelco or Dana?

 

I couldn't really tell you but FWIW my U joints are original eek: true story)

@ 206,783 miles.....I'm happy with the OEM's ...

 

I had a squeak that started out only happening in reverse, progressively it began to squeak while moving forward too. Just changed out the rear most u-joint today, the one at the diff, now my truck is quiet and I'm a happy camper. Three out of the four caps on the old u-joint looked alright, needle bearings intact, the last one, had only dust in it, which I'm guessing is what was left of the needle bearings in that one.

 

What u-joints did you decide to go with? Thinking about replacing mine.

Camelbak Toyota has them listed at $52, but aftermarket's are less than $15.

 

I haven't decided yet, one dealer said $70, rock auto has them from $5-$30. I won't go w the cheapest but it's not clear if Toyota is really 2.3 times better..
