Interesting. We have a 2004 and the interval is 10 years or 100,000 miles. They must have made a radical change in the coolant.

Long life coolant is silicate free.
It's cheap insurance to change the coolant every 2 years or 30,000
also change the thermostat while you are at it
Changing the coolant with the good stuff (silicate free)
It will increase the life of the water pump and protect the metal parts in the cooling circuit and allow better cooling efficiency

I had the same problem which the dealer fixed completely under extended warranty.
 
The job was valued at over $5000. (3600 on extended warrantee, the rest on regular warantee. I did have to pay $50 for half of a 4 wheel alignment
 
They found the rear bushings were worn out. This was causing rear end sway plus noise over bumps and excessive tire wear on the edges.
 
To replace the businings, the had to replace both swing arms assemblies which also include the bearings for the rear wheels. The springs were sagging so they replaced them also. The net effect was an entirely new rear suspension for free. The car is 2003. The work was performed 2008.
 
Previoulsy I had another $3000 of waranty work done on the front end including new stabilizer bar mounts, and at least one new bearing.
 
The trick is finding a dealer who is hungry for the business. Some just don't care. When I first had undercarage noise with the highlander, I took it to the dealership that sold me the car. They told me they were going to have to do a diagnostic and road test (at my expense) before they would tell me if the work was under warrantee.
 
Next I took the car to another dealership closer to where I work. They were happy to undertake a comprehensive warrante repair. They are a somewhat remote from the city core and hence eager to go the extra mile.
 
One more thing to keep in mind. The parts took a long time to get and I had to do without the highlander for more than two-weeks.
 
Its important to get these things done under warrantee becasue after the warrantee is up, it would cost less to scrap the car and buy a new one

Has anyone ever re-torqued the drive shaft bolt on a HL? If so was it necessary, thanks.

The only procedure I could think of would be to fully loosen and then retorque to specs. USELESS procedure IMMHO. My 2001 AWD RX300 calls for that and has ~70,000 miles....
 
Since most owners will not own a torque wrench this is most likely simply a way to get you to "visit" the dealer.

I had the dealer do it at 15,000 miles since it was in the scheduled maintenance. I have no idea if it was necessary or not but since Toyota recommends it every 15,000 miles, I will probably continue to have it done. I have a torque wrench but no good way to lift the vehicle up and support it.

I never did it, and my HL went 121,000 miles without a problem.
 
They only suggest doing it if you drive under the "severe" classification.
 
I would not recomment loosening then re-torquing.
If it aint broke, don't fix it.

07, 4 cylinder, AWD Question by andrelaplume
May 01, 2008 (11:28 am)

Dad traded his 6 cylinder for a leftover 07 (old style) HL. Its automatic, AWD and 4 cylinder. He says it peppy but he only gets 20mpg on the highway! I said this can't be right. The dealer says they may need to reprogram the computer...HUH? Anyone ever hear of this? Anyone with any real world mpg with this model HL?

my 2003 V6 HL averaged about 20 mpg (mixed commute / freeway)
If I drove freeway only at 80-85 mph, it would get 21 mpg
 
my new 08 HL gets 21 in mixed drving and 23 on the freeway
