Truck makes weird noise please help thankyou.

Sooo I noticed today that when I reversed my truck only in reverse it makes a squeaky noise. Anyone know what can cause this and how to fix it. Thanks.

2006 tacoma 2x4 4 cylinder single cab with 90k. All stock.

 

Need more detail

 

Lift truck, put in neutral and check. U-joints. Being 2wd I think you never greased them.

 

how do i grease and can i grease them?

 

If they squeak, after running for 90K, its way too late to grease them. Check to make sure thats your problem and replace all of them. Grease ujoints every 5000 miles.

 

can slap shifting do this? I have a automatic truck?

 

How you grease them though just spray lithium grease over the whole u joint? can do it while it on the truck?

 

You need a grease gun and you put the hose end of the grease gun on the grease zerk on the u-joint and pull the trigger. You will have to watch the seals on the u-joints to make sure you don't put too much in

there zerk fittings? didint know that

 

how many for the base model? I dont see any

 

In the picture it appears to be inside the yoke of the driveshaft, as in the zerk comes off the middle of the u-joint and is angled outward, also it should be two, one on the front (near transmission) and on rear (near the axle)

 

Do i have to change it right away or can i get away with running it for a while? if that the problem

 

Only the 4x4 driveshafts have the grease zirks...
Prerunner/base don't
I need to change out my u-joints on mine

 

Could be your power steering belt if its a high pitched squeak. Spray some wd40 on your belt and if it stops then tighten the belt.

 

The newer Prerunners do have zerk fittings. At least mine does.

 

Your going to want to fix them ASAP. Running bad U-joints can cause big problems, Ive seen warped shafts from ujoints giving out at high RPMS.

They also become more and more of a bitch to replace once they seize and start melting to eachother.

If it was the belt it would be making the sound at start up no matter if hes in drive or reverse or even park.

 

Mine did it occasional but at first it was only in reverse at full lock.

 

Probably at full lock because the power steering was being strained causing the belt to require more work.

 

it a squeakk ..... squeakk....... squeakkk..... Happen more when i go faster in reverse.
