#7 of 31 Toyota 4Runner 2004- Deep loud repetitive pinging in engine
Dec 18, 2007 (4:40 pm)
my toyota has 48K miles on it. about 6 months ago I noticed a slight muffled pinging in the engine-mostly when going slow or in city traffic--its grown into a large deep ping-sounds more like a hole in a muffler than an engine problem--but its coming from the engine. I just took it to the dealer--they called and said I put too much oil in it--that isnt so-I have it serviced religiously and just checked the oil 2 days ago--they went on to say it was going to cost 5K to fix-but didnt tell me what the problem is--except said there is too much oil in the crankshaft. Anyone ever heard of the noise I am having with the car??other than the noise it drives great and I love the car? Suggestions? advice?

Rather hard to diagnosis over the net but it from your description, it sounds like a bearing noise. Does it happen when accelerating, under load?
Too much oil will cause "foaming" and if left that way for a period of time, it will cause bearing failure.
Dealer didn't tell you what the problem is and said it's going to cost $5,000?
Get a second opinion from another shop, preferably a local shop.
Let us know.....

Downhill assist uses the anti-lock brakes to control the speed. I suspect that is what you were hearing and feeling.

Almost a year now, I have been hearing this noise like water boiling in kettle and occasionally twig braking sounds coming from under the glove compartment. There were also water leaks on the passenger side mat on few occaions. I take my car services to Toyata and they claimed they checked and found no problems and for the water leaks they said they drained the AC water hose and should not recur. For the noises they said they have not heard any. I hear the noises when I start the car and for the first few minutes while driving but then it fades away. Please help why is this happening
#12 of 31 2001 Toyota 4Runner front left suspension noise
Oct 20, 2008 (8:33 am)
I have a 2001 toyota 4runner w/ 76K miles. No accidents or issues. The help I need is that:
I have a "clunking" metal noise that I can re-create occur when I make a hard turn to the left. My CV boots are intact. My steering is excellent at any speed.
No vibrations in the steering wheel at any mileage.
Important note: this is the model year which there is a front left BALL JOINT issue from time of the manufacter. I am not sure if it was repaired.
Important note also: the noise does not seem to occur at temperatures below 35 degree's here in Colorado. ( i.e., expansion and contraction of metal parts)
I recently had my shocks and springs changed.
I do see worn bushings on the front control arm and stabilizer bars ! Coulod this be the problem? What is the best way to isolate the issue?

For the water boil/leak on passenger side-
Definitely a heater core leak. The engine coolant is routed through the radiator to cool it down. Someone figured out that if you routed it through a miniature radiator and blew air through that into the compartment, it would make a good heater while helping to cool the coolant down.
Now, the coolant system is under pressure. If a small leak occurs in the heater core (which happens from time to time as they are usually metal and will corrode) then the pressure/temperature combination will cause the coolant in there to boil, and it will leak out as steam which will condense and leak in the compartment. The AC has nothing to do with it.
If you are interested-
With the hood up, you should see a big round cylinder at the passenger side of the firewall (that which separates the hood area from the interior.) This is the cover for the blower motor. The fan for the blower motor is accessible from then inside of the passenger compartment behind the glove box. That is the air side of this. The heater core is wedged up in there pretty close to it all. If you look again in the hood area to the blower motor housing, you will see two (approximately 5/8") rubber coolant hoses. Likely one is running to the radiator and the other into the engine block. They are big, rubber, spongy and flexible, unlike the AC lines which are ridgid and metal. What those two hoses are clamped to near the blower motor housing/firewall is the heater core that is leaking an needs to be replaced. I'd check those hoses where they connect to the core first, just in case that is the trouble.
The heater core is usually replaced by removing the glove-box, the blower fan, and a few screws, then disconnecting those hoses (while the engine is cool and has been off for a long while. It never hurts to have the negative battery terminal disconnected either.) Then it can be pulled out. Its about 6" x 8" x 1" or thereabouts. A refurbished unit should run about 100 dollars or less, and a decent mechanic should be able to knock the job out in an hour or so.
Hope that helps... Merry Christmas.

Hey I had that problems before. Below freezing the front left would make noise, now my front right makes noise. Wheel speed related??
I greased up where my half shaft goes through the hub and problem solved. Now I have to do it on the other side. There is also a bearing replacesment from toyota for it if yours are no good, mine where still going strong at 300kms.
Front Hub Spindle bearing.
#16 of 31 humming like grinding noise when in motion please help!
Apr 23, 2009 (3:39 pm)
ok i have this humming or grinding noise when ever the t4r is in motion. im pretty sure its the driveshaft. first of all i started to
1.hear the noise
2.whenever the truck is in motion ill let it coast and shut it off and noise would still be there. when in park i brought the rpm's up, there was no noise.
so this eliminates the motor
3. i checked wheel bearings by jacking up my t4r and tried to move wheel to see if there was any freeplay or slop there was none.
4. i then greased the brake pads.
5. i then took it out for a test drive.
6. still the same
7. i greased the ujoints and took it for a drive. 8.still the same.
9.then i greased the driveshaft its that slip yoke type and it got worse.
so could this mean i got a bad driveshaft?
and i also added diff gear oil.
did anyone have the same problem?
