Front end Detriot trutrac

[99runnerwa]

is any one running a limited slip in the front of their ADD IFS runner? i am wanting to install one in mine but i am being told i will have to install manual hubs. i have also been told that i wouldnt have to. if some one who is running a limites slip up front could give me some insight. if i have to go with manual hubs i wont be able to afford it which really sucks.

i know some 3rd gen owners have a tru trac up front with add. Im also wondering if anyone has the correct part number. I looke and Eaton's website is confusing.


you will not need manual hubs. heck at that price you would be better off to go with an arb

not sure what the part number is but here is a site that will install one for you

hit up LINY4runner, he just got a true-trac a couple weeks ago in his (ADD also like all 3rd gens).

I got one.
part number or code - 911A342 -FRONT

 

[brian2sun]

I got one.

Oh yeah, I forgot you have one too.

maclean, do you run manual hubs? if not have you had any issues? also i see that they dont recomend any tires above 32, is that just a cya statement or is there a structural issue?

they dont offer a tru trac front. I know they can do anything with diffs, but I know plenty of local places to get diff work done.

and like brian2sun said ALL 3rd Gen 4runners came with auto hubs. there may be a few exceptions, But all later ones 2000-2002 will have them.

you will be fine. i know someone that beats the heck out of a front trutrac with add and with 33s and is fine.

I have ADD and have had zero problems. I think it all comes down to who does the install.

I am currently running 33's and plan up moving up to 35's in the next year. I would think that the weak link would be the CVs. As I understand it the Tru Trac is stronger than the stock carrier it replaces.

I personally don't see any reason why the trutrac would get damaged or worn out because it's turning when in 2wd (due to ADD). There's still no power going to it and they make them for the rear too and those get action 100% of the time and don't have problems.

When in 4wd, you'd have your hubs locked anyways so there wouldn't be any difference there either.

I had my front diff built by ECGS- awesome guys! Definitely a quality build.

As for the front LSD- in 2wd it feels like factory...there is no power going to the front so the LSD won't be "active". I've even run it on dry pavement in 4HI and I see no need for manual hubs. The best way I can describe it, is that it feels like your front tires are aired down to 10psi.

Agreed. Steering wheel just wants to return to center.

after doing a lot of web surfing i have found a coupple of posts on this issue. from what i have read the DTT that most people install are ment for the tacoma with manual hubs rather than the add. the issue that this brings up is that with manual hubs the carrier doesnt turn, with the add it turns constantly. the DTT does not have bearings like the stock carrier so there is a lot more wear on the axle shaft. also some people talked about pulling to the left while in 2wd. pretty much all of this info was from pre 2008. in 2006 a guy posted that he was doing beta testing on an add version but there wasnt any new info after 2006. if any one knows if they have come out with an add version i would like to know.

Like I mentioned before, the Truetracs were first developed for rear ends which are constantly under power and cycling. If they can hold up in an always moving and always under load rear end, why would you think that running them passively in the front would hurt them? That doesn't make any sense to me, they are plenty strong to hold up in a rear end so the front will obviously be fine, with or without manual hubs. In fact they would hold up if you drove in 4x4 100% of the time. I can't believe they don't have bearings in them, what else would they use?

I haven't had ANY issues like these or otherwise with my Tru-Trac in the front. 2WD you feel nothing, 4WD it feels like the tires are aired down.
