Adding my GX to the list of down GXs. Bringing it to a reputable off road Toyota shop in my area to diagnose a metallic clicking sound when turning slowly, and sometimes over bumps and heavy braking. I think we are looking at CV axles as the clicking has gotten louder over the course of weeks.

Is it unusual to have worn CV axles at 78k miles with 1.5" lift and stock tires/wheels?

Sound unusual but its always possible road debris cut the boot.

Sometimes it depends upon the CV boots. If they're torn it'll let a lot of grime in the CV's which would cause premature wear.
Usually CV boots get torn up from off roading. Have you done much off roading? Being a So. Californian myself, I know a lot of the off road trails can have under lying brush and such that could tear boots.
Hoping it's a cheap fix and you're on the road again soon! :cheers:
 
I would say it is uncommon for the OEM CVs to fail from wear at 78k with a small lift. If it is a bad cv, the likely culprit is a torn boot that let crap get inside. I have seen on here/GXOR where little tears in the boot don't really release enough grease to notice but let enough mud in to ruin the cv.
 
I can't see any tears or cracks on the boots and they feel solid when I squeeze them. There is also no obvious grease slinging like you'll normally see.

I'll find out by this evening. Should I expect about 3 hours of labor for both CVs?
 
Yes, my 19-year old axles have 200K on them, I'm up 3", and they are fine. the only way you should have axle problems are if the rig is driven with torn CV boots for a long period of time, and debris get in the joint and cause wear. If the boots aren't torn and haven't been torn in the past, it's probably not your CV boots.

Wow, 78k? Mines still rocking the factory CVs at 205k. Anecdotal as it may be, it is what it is. Did you buy the GX new?

Update- the skid plates were clanking. the nuts in the frame from back of engine skid/ front of trans were gone and they have been rattling.

saved myself a lot of money but still gave business to the shop to drill what was left, put a rivnut in, and replace all the sheared bolts.

Nice! Glad it was something simple!

Ill find out Tuesday or Wednesday if I need heads. I found a pair fairly close.

Why would you need heads unless one was cracked? What are they charging for this repair?

If they are warped more than 3mm they are paperweights.

To do the headgaskets is 5150.

I was quoted 2300 more by an independent shop, that didnt include a loaner.

They probably lack the resources to do it with less labor hours.

Or mill them down for really, REALLY high compression! 😁

My first toyota was like that. Was a 22R in a 4th gen 5 lug hilux. Weighed about 2300 lbs. After the third head shave it had to run 93 or it would ping. And it pulled noticeable harder above 5k rpm.

That truck got a pre-runner conversion with a Icon(Donahoe) Long travel UCAs and a lock right locker. It wanted to go over everything at 50 mph.

Where in the FSM is this 3mm specification found? Is this what the shop is saying? 3mm or approx .012" is quite a bit more than I would expect. IIRC there is a "standard" warpage depending on where its measured on the head and a maximum warpage of 0.0039 ish let's say 4 thou. There may or may not be a specification listed for how much can be removed from the surface to bring this back into spec. I would bet my next paycheck you can take 0.015 to 0.020 off with NO issues. If they do resurface, MAKE certian that whomever is doing the work understands what surface finish is required for the type of gasket you are using.

I have no idea why it is that way, just regurgitation of specs.

I could talk out my butt on why I think it might be that way, but as an Engineer I dont understand the context of the constraint(3mm), either.

Work is being done by an experienced master toyota mechanic i think my service advisor said he has like 20 years experience.
 
Looking at some flavor of ironman coils to get my front spring rate up. Not sure which one.

My odyssey 24F appears to be bad. Has 2 more months of warranty.
 
I've had bad luck with Ironman coils, front and back. I'd suggest Dobinsons coils. Aussie-made instead of Chinese made. I'm now running Dobinsons in the rear.

3mm may be the maximum compression before piston - valve interference, hence bending valves or breaking piston rods.
Or beyond 3mm milling, one has to use 105 octane race fuel or may not be able to advance the spark enough.
Okay, as you you mentioned in your post, this may be some sphincter speaking here. No real data to back it up.

I was thinking that the hardened aluminum may only be so thick and only 3mm could be taken away before it affected the structural integrity of the head since its possible to sell a thicker headgasket to otherwise offset the milling of the cylinder head.

Kinda like the spiny cylinder liners used in the bores that are not serviceable.

But I have zero data points to support that bull 💩 notion.
