What have you done to your Tacoma today? 1st Gen Edition

I'd like to switch to ADD from manual hubs, but then my front diff and driveshaft will be spinning all the time and that's a lot more drivetrain loss than just the front cv's.

 

lol its really not that big of a deal. Idk why people think it is. Literally every other 4wd truck/suv in the world does the same thing. Including...tacomas! haha Plus if you're adding things like armor and loads of camping gear...you really think that a small amount of rolling resistance is really impacting your truck and how it drives more than a front bumper? Hell no.

Now, granted, if you have manual hubs, why bother. There are some improvements for sure. But cost and time? eh. Whatever. But spending money to go from ADD to manual..insane. At least to me. Weaker CVs, weaker hubs, PITA to change, require some form of maintainence, and also just a hassle to use and in my case can literally freeze over in the winter. Just not worth it.

 

I only went to manual hubs because it was easier to do during my 4wd swap, got a steal on a j shift t case, and bought a locked front diff. Now that its in I really wish I had ADD so I didnt have to lock the hubs every time I put it in 4hi

 

Yep. Manual CV axel diameter on is 7% smaller compared to ADD axel diameter. That worries me a bit. I realized that a bit late.
My passenger side bearing is making the same periodic noise I heard in my 67 Mustang before its front bearing failed many years ago and my inner CV boot groove is pretty deep on both sides. So now is a good time to try out the manual setup. I will be replacing the ADD hub bearings so I have a backup. if something fails on the manual I can swap back.

 

Unless you have a full time locker in the front the only thing spinning with ADD in 2wd is the CV's, side and spider gears. The diff carrier, R&P gears, drive shaft and t-case 4wd components do not spin.
I'm also beginning to feel that there is some benefit to "exercising" the boot rubber.

 

You can't swap unless you swap hubs. The ADD axles are 27 outer spline and the manuals are 26. They don't share the same parts.

Again..weaker link.

interesting thought there.

 

Here is a bit of "CV logic 101" when sourcing replacements.

Given this generally accepted premise, "CVJ is a reputable vendor/rebuilder of CV's.

They state "we only rebuild OE CV's".
Further on they state aftermarket new (Chinese) CV's can not be rebuilt.

Therefore, they are implying all rebuilt/rebooted 1st gen CV's are OE.

Totally get that. I did the best I could by shooting some gun cleaning lube into the latch area. Wiped it out with a rag and repeated a few times. I guess if it fails soon I'll have to remove the latch part and do what you've done.

 

This is really trivial, but I bought new wipers and and cleaned my windows (both inside and out). Amazing how little things can make a big difference sometimes.

 

Got any pics I can add to my collection?
No pun intended.

 

Here's what I have.


You can see the engagement nob was destroyed and the brass bushing had some pretty good scouring and deformation. (5 year ago you could not order just this part, maybe it's changed since.) The needle bearing was pretty well chewed up also.



ADD vs Manual stub axle difference.

 

Thanks man, added to the collection.

 

@Wulf don't you have some manual hub/axle carnage you could add to this collection?

 

Advance Auto CV

 

Unless you have the manual hub intermediate shaft like me instead of the stub shaft on the ADD intermediate shaft assembly.

I only say that based on from what other people have told me. Where are they switched from manual hubs to ADD spindle and CV with the manual hub intermediate shaft on the diff. But you're probably right.
I thought on ADD trucks, the front drive shaft doesn't spin until you engage four-wheel drive and the ADD actuator engages the other cv axle

 

Thanks, added to the "inner joint" folder.

 

That is true, on factory ADD trucks the front driveshaft is disengaged in 2wd. I can crawl under the truck and rotate the front driveshaft by hand to grease all the zerks.

 

Having swapped my ADD hubs for manual hubs, I would agree with most of the sentiment here. The benefits are not worth it in retrospect. It gives the truck an "old school cool", but that is about it. I haven't noticed much gain in MPGs, and makes maintenance a bit more time consuming. Some serious carnage above . I have yet to break mine, but I'm sure it's only a matter or time....

... So anyone interested in some used manual hub swap parts I have for sale?

 

I think I have an ADD stub shaft you can have. Might not be the cleanest thing as it's been sitting in the junk pile a while now.
