If its a V6 with #6 misfire and mostly happens when it sits for a while then its the head gasket. Seen plenty and done a few, Spark plus i doubt it i've seen these with 260k on stock plugs and it still runs perfect which is crazy for a 30k plug.. Im a Toyota Master tech if it matters.
Testing...
Find a dealer to do the T-belt its surprisingly cheap i think our dealer charges 599 for the full kit.
I have never changed the washers for the diffs and never had one leak in 8 years wouldn't worry unless you have done it a few times.
Just do a simple drain and fill on the tranny, we have...
at 7500 miles still have the noise, I dont drive it very often but my wife does. I'll try changing the KDSS cylinders at 15k or something when i have time. I can do it anytime i'd like but work has been busy and i've been lazy haha
The noise is profound it almost sounds like shock tops in older camrys that are shot. Only left turns does it pretty good around left turns that have dips but will do it when straight. I sent a tech case to toyota they haven't seen any issues:frusty: I can't find anything wrong and dont want to...
So i checked the warranty labor times that usually extended 3rd party groups would pay and its 12.7 to do the front cover and that will reseal everything but the rear main seal, rear main seal pays 4.6 hours so you are not even close to 20 hours in labor. Parts wont be to expensive maybe 300...
The people who change your oil get paid dirt, they are noobs who only change oil but they suck at it. To get a master tech you need to usually come in with a concern with your oil change. The people i see who change oil only i wouldn't let them put air in my car.
Can't remember on the 4unner but when i scanned a new sienna van it had 36ish computers. I think the 4runner will be close to 20.. If a 4runner comes in for a CEL i'll check.
Sorry guys I've been swamped at work and haven't had time to look at it, but its still making the noise on left turns.
Its definitely not the tires as mine did this with 3 miles on it, It shouds like both kdss hydraulic shock things are collapsing.
There is a guy on Tundra forums who made his tundra AWD. It wasn't bad but you need the buy a limited transfer case and lock the front ADD switch hook up a few things and thats it. But it would probably be cheaper to buy a limited and put trail edition body parts on it.
Haha i was wondering if i should of posted that im a tech... Yeah i know the cylinders are on the left side thats why im thinking its kdss related i can go straight over bumps and no noise, its only left and when you hit a bump very weird. Maybe next week i'll hook up chassis ears and pin point...
