The Firetruck build

So evidently I'm dumb - I didn't even know there was a bright red Tundra color. Looks sexy as hell! Mind sharing some of your mods (especially the lift)?

 

I can't tell if it's Inferno or barcelona red. I'm leaning Inferno.

 

Radiant Red, only ran for 1 or 2 years on the 3rd gen I think.

 

So there is no safety Cotterpin anymore on the JBA ball joint nut, or is the angle of the pic hiding it?!

 

Nylock nut, essentially does the same thing, just dont reuse nylock nuts.

 

Interesting, guess thats better than nothing - but no way I'd bet my life on a piece of nylon plastic personally... My tubular UCA's re-used the factory nut & cotter pin, had no idea JBA did this. Thanks for the info.

 

Theyre both mechanical locks. You do bet your life on it though, so to speak, at least assuming youve been on a plane. Nylocs are used for fasteners on airplanes.

 

In my experience anything of importance on aircraft is generally wired; however, keep in mind they also receive regular inspections too - unlike automobiles.

 

Seats, inner doors used nyloc on paneling and mount points.

 

What did the MOOG lowers get you? We’re yours worn out?

 

I understand this, but its just not a fair comparison - as you are talking about aircraft which are constantly inspected by highly trained mechanics, who have to prove on paper that they ordered a new nyloc nut during a maintenance cycle.

It just doesn't seem like a smart move to use a Nyloc on an automotive upper control arm, in which down the road some kid will buy the truck - and maybe he will change the struts - you really think he is going to know and/or special order a new Nyloc spec'd to that ball joint? Its not going to happen, it will be re-used and any future owner will be risking their lives driving the truck.

I realize the odds of a Nyloc nut falling off on the freeway are likely very low, but why take the chance? What is the upside? As I said, my control arms (which I don't even like all that much) were able to use the factory Toyota nut which is secured with a cotter pin - so why can't other manufacturers do that too?

I also looked into Nyloc nut use on aircraft and found this fascinating article (for anyone who is really bored...)

https://code7700.com/case_study_eurocopter_as350-b2_n37sh.htm

This aircraft used Nyloc nuts, but it was designed as a redundancy - so the Nyloc's used Cotter Pins too; this helicopter company apparently re-used their Nyloc's (against Eurocopter spec) resulting in them being useless - and then a mechanic most likely forgot to put a cotter pin through the used-Nyloc - this resulted in the helicopter crashing and killing all five people. A simple cotter pin would have prevented this according to the helicopter manufacturer:

"Eurocopter stated that even if the bolt and nut were improperly torqued or the nut [Nyloc] was degraded, the split pin should have prevented the loss of the nut."

 

Good stuff, thanks.

I suppose if anyone is concerned or has time there are 195 pages of Tacoma dudes running these with pretty much no major issues. Could search or ask about the nyloc nuts there. I searched but found no issues with the ball joint nut nyloc nut mentioned.

Yes, but the risk is really several years down the road - that second and third owner who choose to change the strut and who re-use the Nyloc nut out of ignorance; a cotter pin nut makes things black & white for the less skilled. JBA is still fairly a new company, give it a decade and lets see how all these Taco's running around with used-Nyloc's are doing...

 

Agreed, but by that statement, any assumption that they would fail is equally as valid as the argument that they wont, so long as we discount that they haven't failed yet. Lest you can provide evidence otherwise. At present there are people running JBAs on their Tacomas for 6 years now, so far it hasnt been an issue.

Also, JBA has been around for about 17 years now.

 

Many other name brand, well known companies use a nylock nut on the UCA to spindle bolt. This is very common in this industry. I would hope that people regularly do a visual inspection of their vehicle, I know I do. I also do all the work on it so I also know what to look for and what items to have excess stock on hand, i.e. extra nylock nuts.
