2003 Lexus GX 470 Service question
I just purchased 2003 Lexus GX470 with 185K miles on it. The guy I purchased it from had no records of any previous service. Car runs smooth and no issues so far but I am thinking about getting up to date with service like TB change and WP replaced. Anything else I need to replace at this time?
#2
What is TB and what is WP? Those things aside, I just bought an 03 with 170,000 with sketchy records as well. The first thing I did was change oil, both differential oils and Transfer case. I also lubed the drive shaft, and siphoned out some of the old Power steering and brake fluid (not a full change or flush). I need to pack the wheel bearings and a coolant change in October and I think I'm good. My transmission oil still looks good, but I'm almost certain it has never been changed so I'm not sure what to do about that.

Ok, TB is timing belt. For those of you that don't know, there is a way to get the Carfax service records for free. You sign up for a Carfax account, and then go to "my car maintenance" and "track your car's maintenance". You can add a car by entering your VIN number. and that will give you access to any service records on your car. It costs nothing. It will not tell you about damage reports or any of the other stuff a carfax report tells you,

TB = timing belt, WP = water pump, easiest to do both at the same time. Coolant flush at the same time is a great idea.
I don't believe you can repack the wheel bearings on these trucks as they are sealed units.
All fluids and filters is a great place to start when baselining, including cabin air filter as they get nasty.

Or, that bearing can be pressed out/in, etc.

Tire rotation should happen with every oil change (5k miles) to get the most life out of them.
If you didn't get the owner's manual(s), they're available on the drivers.lexus.com site. You should enter your VIN and contact info there, so they can notify you in case there's ever a recall.

Rotating tires at 5k intervals? Overkill.
#12
It's in the GX470 service guide.
And for the typical owner, it's a good compromise between doing it too often (like the 3k mile interval that some places still recommend...) and a sludged-up engine.

1st gen GX, do you really care what the service manual says (unless you bought some warranty or something) ?
Overkill on replacing fluids and such can't hurt, your $$, spend it any way you like.
How many have dumped the trans pan and replaced filter and put new oil back in? I have done mine twice, but the manual does not show that, so should you not do it?
