#12 of 31 2001 Toyota 4Runner front left suspension noise
Oct 20, 2008 (9:33 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!

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?

I own a 06 Tacoma already has 92,000 miles on it and has the same problem i been told that the differential have to be replace it wore down. and if you ask at a dealer they will ask a lot for the part, better going to a 3rd party research the prices before you buy it get the one with the best deal on it.

I think I've got the same problem. Did you ever diagnose and fix this? I'd really like to hear about it.

2002 4runner Sr5 makes rattling noise when standing still or backing up. In park there is no noise or when I am driving. Silent airplane noise when I am accelerating. One mechanic said torque on transmission. Another the exhaust system. Help.
