Rear Lower Control Arm Bolt size?

Found the part number. None of the dealers around me. Need the bolt ASAP. Anyone know the size?

Lower Control Arm Bolt - Toyota (90119-14118)

Halp. Stranded on the side of the highway trying to figure out where I can get one.

 

I think it's an M14 about 3 to 3.5 in length.
Any ideas?

 

No idea but it looks like both sides are the same. Can you get to the other one?

 

do you have the bolt in hand/able to be measured?

buy a bolt gauge, or see if the dealer will give you the dimensions. McMaster carr sells everything and arrives next day.

buy the same grade, or risk death.

 

Wait a minute…

how do you need a rear lower arm bolt for a newer truck?

might be close enough in size to some grade 8 metric you can get at Home Depot and simply cut to length if off. Thread a nut on before cut to ensure you can clean up the threads to resssemble.

 

Orginal bolt literally lost on the highway. Limited tools and nothing to measure so couldn't really pull the other one until a friend arrived and saved the day. M14 grade 8 is the temp bolt in. Waiting on OEM replacement.

 

Your guess is as a good as mine. I've done a lot to the truck but never touched those control arms in the rear. An M14 grade 8 from HD worked for now. Waiting to get OEM replacement.

 

Mine just fell out of the GX460. Did you confirm it is an M14 about 3-3.5"?

M14 fine thread 90mm long
9/16" bolt about 3.5-4.0" long would typically work as well, being just 0.28mm larger dia. than 14mm.

 

Yes. M14 with 1.5 thread pitch. 3 1/2 inches of shaft length. The washer does not come off of mine so I presume it is included on the replacement if you go the OE route.
FYI, Lowes and HD didn't have any hardware as big as M14 but Ace Hardware did.
OEM part numbers:
90119-14118 bolt
90178-14011 nut

 

That does seem odd. Makes you wonder if the bolt simply snapped and fell off. Who knows if maybe other changes you made changed angles and ended up putting an odd stress across that bolt.

Once you get the replacement OE bolt, it might be worth inspecting the hole and bushing on that trailing arm for any evidence of damage. The hole might be wallowed out or otherwise damaged, which could lead to the same outcome if you re-use the trailing arm. It’s just too weird for a bolt like that to come out for no reason.

 

Measured off my rig just now...





M14 x 91mm

 

Off-road miles tend to loosen fasteners without any threadlocking feature. On my Tacoma, I've had front UCA bolts, lower shock bolts, leaf hanger bolt, and even sunvisor screws back out. The leaf hanger bolt was mostly out, with just a few threads wedged in the shear line between the clevis lug and leaf bushing, so the rear axle was close to departing the truck. I changed to M14 nylok nuts at all those critical joints.

 

Americans will measure with anything but the metric system, even on metric bolts
