Lbj bolts again

Ok so I know there has been some threads on this but I need confirmation. The write up on adventure taco for lbj has only 1 part number for the bolts. I’m not putting the rubber boot back on so am using the flange head bolts. The old bolts have a few more threads on them and are longer. Am I supposed to use the same size bolt in all 8 holes? Or am I ducking up here

 

If you aren't going to use the dust boot, then it is the ARP bolt. Torque to 59 ftlbs.

See below for reference.

 

Ok, but the dust protector doesn't go around all 4 holes. So how could the black bolts not be right… esp if thet are stronger

 

The black with washer are slightly longer due to the added thickness of the protector. 2 holes are pass-thru so it doesn't matter but the other 2 are not.

Dust boot use the black w/washer

no dust boot, the ARP bolt

or whatever you want - your ride, your call.

The two bolt holes that aren't holding the dust boot on go straight through the knuckle, the ones that hold the boot on don't.

I broke a bolt off in one of the non-outboard holes when not using the dust boot and it was a pain to get the broken half out because you can't get to it from the top.

 

Right. But the protector only goes between 2 of 4 bolts on each side.

do i order 4 long black bolts & 4 short bolts??

 

Got it .. I have the shorter bolts and am not installing the dust protector. Just seems like the bolts that thread into the outboard side of the spindle would be longer.

 

If you are using the dust protect then you order 90119-10933, so if replacing both LBJs, order x8 bolts - 4 per side.

If you are NOT using the dust protector then order ARP bolts

 

9008010066 - 59 ft lbs

 

That's the green bolt. Each to their own of course. It's all a judgement call in the end. I guess if I was going to stick with OEM then I would go with the green bolt over the aftermarket ARP bolt.

 

is this cap?

 

If its an OEM part rated at 59 ft lbs, it's fine. Most LBJ failures come neglect of maintenance. End user just needs to pick a bolt, use the correct torque and call it a day.

I bought the black bolts but torqued them to 59 instead of 37 ft lbs because of lack of research. I'm still daily driving the truck 70 miles a day like that for the last few months. I don't know if its safe to undo the bolt and retorque or to replace the but I ordered 9008010066 to replace them and to remove the boots, but havent had time to swap them out yet.

 

Its not safe. I wouldn't drive it until you replace them. @59 they are at their failure point.

 

I figured that much. I' have 7500 miles on them since replacement.

 

Slight twist on the same old issue and a concern. I just replaced my LBJs and specifically purchased the black 901191090933 bolt @37lbs for my 96 6 lug 4x4 after reading up on the spiker LBJ thread. I do not have dust covers. I checked penetration on the two non-thru threaded holes before installing the bolts. Even pre threaded bolt into the hole to check how far it would seat before installing with LBJ. Seemed to seat fine and torqued with no issues. Now yall got me worried and wondering if I should have used the OEM bolts that came with the LBJs instead.

I wonder if the threads are there for some folks but are gunked/rusted up in there where the original shorter bolt did not protrude, causing longer bolt to seem to bottom out early.

Should I be concerned with my install?

 

If its seated completely and you torqued it to 37, call it done. As I understood it (from other posts which I can't find at the moment), the 90119-10933 was slightly longer to accomodate that damned troublesome dust cover. If its fully seated and you didn't have any abnormal resistance snugging it up and then torquing it, don't worry about it. Maybe it was on the 02-04 where it was an issue. I honestly can't recall.

 

Thank you much. I will check up on it a few times going forward. The black bolt is indeed just a tad longer than the old OEM bolts and new ones that came with OEM ball joint. I checked that length first and exactly the reason I did the black bolt test fit without the LBJ.

 

Leon's Preload chart (below) sold me on using the OEM 90119-10933 black bolts torqued to 37 ft./lbs. when I retrofitted the LBJ Protector boots to my '97 V6 Taco 4x4:

 

@leid - You mentioned this earlier about the 03 FSM showing 59ft lbs. FWIW, that widely shared and referenced copy of the 03 FSM available online in the archive was at some point corrected by Toyota. The current data from toyota shows the dust protector and 37ft lbs spec in the illustration and instructions.

This appears on 02-04 FSMs.


For the 01 model, the fsm shows both values. What it does not mention and should, the difference in bolt part#s. If anything still needs to be corrected, it's this.

2000 and older it shows-

(Note to anyone who didn't review previous posts, you DO NOT EVER torque the black w/washer bolt p/n 90119-10933 beyond 37ft lbs! NEVER, EVER, NEVER lol)
