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

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

Generally, that is the accepted theory - but it is possible under certain driving conditions especially, for the 6 to exceed the mileage in the 4 cylinder. The weight and drag co-efficient are more determinant of the gas needed to move the mass, than the number of cylinders doing it. Again, especially under certain driving conditions.

I have 2004 4 cyl 2wd Highlander rated 27 mpg on highway and have no problem getting that figure at 65-70 mph. Believe the 2007 awd 4cyl is rated at 25 mpg, if he's doing very fast speeds, no 25 mpg is possible.
