DANA 35 Truetrac

[cmax13007]

Anybody that has a truetrac for their IFS dana 35 know what where I can get the spring kit. Not even sure its needed. One local shop told me its for keeping the inner axle shaft in the differential (not really sure). Part numbers and pictures would be awesome. Thanks,

There is a TrueTrac for the Dana 35 in that dinky custom Ford IFS diff??? That's news to me.

They do not currently make one for the D35 IFS, only for the last-generation D35 TTB. The side gears that engage the axle shafts lack the proper circlip grooves in them to engage the corclip on the end of the axle shaft. If there's a kit to turn them into full floating axles, I'm not aware of it. If there's a kit to retrofit that TruTrac carrier to accommodate it, I'm not aware of it either.

Now, with some proper measurements and some machining experience, it may be possible to jig-bore the proper grooves in the gears, but it'd be a custom one-off, of course...

CMAX13007, are you aware of some method of fitting the TrueTrac in there? I would love for you to elaborate as I have wanted one of these badly for some time.

FYI, contact Reider Racing about that. I had someone there two years ago tell me that they had done it before. They can do it again, I have been waiting for the Torsen front diff. to fit the D35. They say that that is in the works also.

The torsen is a ways off for the front different. I actually called them the other day to see if they would give me a prototype per customer review. A long shot indeed, allthough I did get all the info on when its going to be available. He said it will be revealed at sema in november and then available in January 2009. I heard on here that it might be available via this summer but thats not this case anymore. Check this out.......

I will get the info about the truetrac on here soon. Bad news, but maybe a way around it. Still doing the engineering.

Thanks, I had spoken with them right after you suggested it. They were still hoping for Summer at the time. I have spare 3.73 diff's that I want to swap for my 4.10's. I was hoping to be able to change the front diff. when having it rebuilt.

hmm Reider Racing...That wouldn't be the place off Eureka road in downriver SE Michigan would it???

I thought they were off Northline, but yeah, that's them...

I was right...

Off Northline in Taylor.

Good people, I've bought two Torsens from them, and lately a pair of Alloy Explorer axles, bearings, etc.

 

[r37ribution]

I bought my 8.8 TrueTrac and 4.56s from them. I had no idea they got a TrueTrac in the X's D35! I thought for sure they said there was no option for my front diff. I'm gonna ask them again.

 

[CDW6212R]

That was at least two years ago, I was wanting a Torsen for the front also. They told me that they had done it with the True Trac, with modifications. I read somewhere that a Torsen has been modified to work in the front also, but that's a Torsen development project. It's still an unknown time away from being available.

 

[r37ribution]

I just tried calling Reider Racing, their line no longer works. Someother company has it onix or something. They said they went under about three weeks ago. I'm going to drive down there and see for myself.

:edit: I told the lady that their web site was still up and she said she knew that, but they had fore sure gone under...

Actually, there is a True Trac made for the front of our vehicles summit sells them. Thank the jeep guys for this one since the development for the dana 30 lead to this offering. (our front case is a dana 30 case with a dana 35 ring gear for those wondering) Check out summit racing. Here is the link http://store.summitracing.com/partdetail.asp?autofilter=1&part=DTL-912A569&N=700+4294925134+4294908331+4294839047+4294907827+4294918887+4294902532+115&autoview=sku not really sure how long they will make them or if they really have any in stock. But good luck to those who try to get one.

Close, but no cigar.

See post #3 above. If you look up the TruTrac in the application guide on the Eaton web site (which is apparently a bad link at this particular moment) they do not even list it for the IFS.

And, no, it's not a D30 with a D35 ring gear... It's a true D35 differential.

ok, so i checked the dana site and they give the same part number for the cases between a jeep and the ifs an ex. I'll take the defeat on the hybrid but then with that information says any locker for the rear of a jeep will fit in the dana 35 case of the 95+ explorer. What is the difference in the axles? What is the problem with fitment of a standard D35 axle? Case clearance?

 

[gijoecam]

The problem is axle retention. The IFS D35 on the front axle of an Ex uses circlips to hold the axles in place. IIRC, the Jeeps use a c-clip design similar to the Ford 8.8. To make that work in a Ford 8.8, you would either need to modify the diff to hold the axle shafts in, or modify the axles to retain the axle shafts they way they do on a Jeep. Either way, the Ex axle components need to be hybridized to accommodate the axle retention in our axle assemblies.

 

[dkchrist]

no problem with the case? An not all 35s are C-clip retention only the dana 35C is a c-clip retained axle (and the one in the front of exs and ranger IIRC) the earlier models use bearing retention. So if you had a bearing retained D-35 then the cases should swap right or am I still in left field?

Also, a side note I think the reason for me thinking the ifs 35 is a hybrid is it use the same axle size as the 30 and carrier bearings. Also the dana 30 are not c-clip retained so this also added to the confusion. Thanks for the info.

BTW, since the link is not working the part number of the truetrac is 912A569 and i think you should be able to search for it on summit.

 

[gijoecam]

There is a difference between a c-clip and a circlip... they are not the same thing. The IFS on an Explorer uses circlips to hold the axles into the spider gears. To remove them, you simply pry/pop the axles out. With a c-clip axle (like the 8.8 on the rear) the diff must be opened up, cross-pin retaining bolt and cross pin removed, axles pushed in, and c-clip removed before sliding the axle shafts out. They're two different ways of retaining the axle.

You'd never want to use a circlip to hold the rear axle in place as the circlip can't resist the axial loading of the axle shaft. The axle shaft would be be too easy to pop out when cornering. You can get away with it on a front axle because the axle shafts on an IFS don't carry any of the in and out loads of the wheel, so there's no significant pulling on the axle shafts (if everything is working properly).

If you still don't quite get it, take a ride up to auto zone and take a look at the driver's side halfshaft. The inner end of the inner joint uses the circlip to hold it into the diff spider gears. It might help clear up the confusion.

I understand the c-clip/cir-clip part I have rebuild both end of my truck and both ends of a jeep. I think I see what you are saying about the circlip groove, is the groove in the splines the spider gear? (never looked when i had every thing apart)

I have looked for an application guide for Eaton products and the newest one I can find is about 5 years old. Does anyone know of a better resource?
