I don't really trust my ADD system. I have spare front diffs and I would like to weld one and replace the open diff I have now. Can I weld an add diff, if so can I perminately engage my ADD and eliminate the vacuum? I search but nowone has posted a welded add front.

 

Just install some IFS lock hubs and disconnect your ADD vacuum lines

 

I did this, works great:

If you want to, you can call up downey, because they made a plate that locks the shift fork in place. i think its like $30-$40 though. FOr that price i am just planning on replacing the add tube with a non add tube.

 

thanks for the link. I think it will be much easier with the front removed, I will prepit after the weld and lock the fork. I don't get the band clamp, does this system rely on a band clamp for operation? that seems a little chincy.

 

I used a hose clamp. Haven't heard of anyone having a problem with it. That mod has been around for many years. Should be more reliable than the vac system, but that never gave me any problems either. I guess while you're welding you could tack it in place if you don't like the hose clamp idea.

 

good idea, I think I will look into welding it in place.

 

If you weld the diff you will be driving the whole front end all the time will you not? Unless you put manuals on the hubs because the ADD only disconects one side and relys on the spider gears for differentiating(sp). Or this is what you are after?

 

Sig Line, I can unlock one side in the winter to eliviate push, I realize the drawbacks of a locked front but the warn's should take care of anything.

 

Flash where you from, looking for some good ON yota boys for wheelin trips

 

Are Warns pretty strong or what?


btw, doing 20 point turns on the trail or having to get out and unlock a hub so you can turn gets old real quick!

I beat the snot out of my warns when I still had IFS. I always broke the gears before anything else. Now that I have done the SAS I am still running warns.

 

[QUOTE=bruzer;50860499]What gears did you break? hub gears OR ring and pinion?

 

I'm in Barrie. Don't wheel, no money for that fun .

 

Warns are plenty strong - I ran them in my 350hp mud truck and never had an issue.

 

I trust the hubs. I figure like this, I have open front now so only one wheel has power so if I ride with one hub unlocked it will be the same as now. If I need the locker I will just lock the hub for those instances it is needed.

 

Well, I've seen lots of Warns break......

Never seen an Aisin hub break... unless they was running longfields

 

bluyota get aisin not warn hubs!!!
come down here we wheel like every weekend!
and in the winter a welded front will be dangerous..
if its a trail rig weldem up if its a dd the cost of tires and wear and tear would have paid for a arb or elocker in no time!

 

As I understand it, its not the Warn hubs that break, its the OEM studs and pins that hold them on. The cone washers with Aisin hub design provide better support and takes some of the stress off the studs.

I just recently switched from Warn to Aisin and found one broken pin I didn't know about.

 

Big T I would love to come down for some wheelin. We are planning a trip to wheel the kilarney area, august 15th weekend, couple of days and hundreds of miles of trails. I have WARN PREMIUM hubs and they work MUCH BETTER than my friends stock ansins. His never unlock proporley, and ar allways a female dog to turn. I have spares of EVERYTHING so if it breaks, I will repalce it. I still think that having manual hubs should eliminate all problems with a locked front right?
