you know, now that i looked at the service manual for the suspension on this truck, i think i could do the whole job myself now cuz the truck is 4.7k pounds (kept on thinking it was 6k before), i did the supsension work on my g35 coupe last year and for the money they wanted in labor i would be willing to do it for some else for 1/5 the money nissan/infiniti wanted me to pay them... it's easy as heck just as long as you have the proper lift ie one of those 64" full size lift from harborfreight (which only cost $69 on sale)... i think i will do mine when the time comes - sensors springs etc
g35 coupe have more sporty suspension with more parts involved so this truck would be nothing new except for the electronic airbag sensors etc which my g35 doesn't have but the service manual covers all that...

For me it's not the work. I can do it. It's just the cost for parts.

I think they are trying to squeeze some cash out of me. Hey claim all 4 shocks are bottoming out. $3000 to replace. $1500 for parts and $1500 for labor. Not gonna replace them yet. I need to do some more research on it. Has anyone replaced them before? I've replace conventional shocks and struts before but these electronic controlled shocks.
2OnyxLexus,

Do you know what the height sensor parts look like? Is it possible to take a picture of the sensor?

Thanks.

RedRocks
No Idea what they look like. Pretty sure you can google it or someone on the forum may have one. I still don't have my truck back yet. I'm driving a loaner they have us. 2010 RX350.

redrocks,

Sensor part numbers are 89407-60022 (right rear sensor) & 89408-60011 (left rear sensor).

http://www.ebay.com/itm/Lexus-GX-470...sories&vxp=mtr

This is a link for the part on Ebay. It includes a picture. I hope this helps.

this is interesting, a member here on clublexus did this to fix the airbag/sensor problem for good but he didn't give details: someone call a mod to help us out

"I swap out my rear air bags for coils and have two height sensors laying around."

hmm???? interesting

ok folks: i googled and found out that there is a:

2003-2009 Lexus GX 470 Rear Air Suspension Conversion Kit

this replaces the airbags/sensors so it's a permanent fix - cost is $400 for the kit rear end, nice ha?
