Rear driveshaft

HELP!!!! Rear driveshaft

Does anyone know the years that the tacoma V6 Xtracab 4x4 rear driveshaft came with 2 5/8" bolt spacing on the double cardan end. The earlier ones have a 2 3/8" bolt spacing on the double carden end. The 2 3/8" works for the front driveshaft of our 80s, but I need the one with 2 5/8" as that is the spacing that is needed to bolt up to the rear of our 80s.
Thanks,
Sean

MTNRAT,

I'm extreemly interested in your findings...just to understand here. Are you trying to get a rear drive shaft with a Double Cardan off of a stock taco that will just bolt up to the cruiser? Is there such a beast? Does the taco come with one stock? That would be great news. Are you then going to cut and turn your rear diff, or are you planning on the Slee adjustable arms. What Slee Springs are you using?

Thanks

Safado, I just want the double cardan joint from the taco driveshaft to cut off, and put on the transfer case end of my rear driveshaft, or to make it the correct length to bolt to the 80. i will have to see it first. I already have adjustable rear upper control arms. I am running 6" slee springs.
Cheers,
Sean

Ok, so not so simple as I thought. You're looking for the double cardan from a front drive shaft then...or do they have them in the rear as well? Are you going to be able to get enough of an angle out of those adjustable arms? Just curious as I have the same amount of lift and am having deceleration problems with the rear drive shaft...thinking about that same solution.

 

[MTNRAT]

Safado, it is not easy to get an answer. It was the rear half of the driveshaft off a late model (2000+) taco 4x4 xtracab V6 that I thought I was looking for. However with help from Cdan it was shown that the flange that it bolts to is the same part number for ALL years so it must be the 2 3/8" bolt spacing. We need 2 5/8" bolt spacing. Cdan gave me a lead on something that may work. I will keep you posted with my search. I have the same deceleration noises as you are getting will find a good solution.
Cheers,
Sean

Kumar (ktp_inacoma on here) put a rear driveshaft from a Taco onto the front of his '96 LX450. The rear driveshaft from the Taco (only 4x4 extended cab versions I believe) is a two piece design, you want the rear-most part of that driveshaft, it bolts directly into a 80-series front driveshaft spot, has a factory double-cardan joint but is the wrong length (needs to be lengthed I think, can't remember).

I don't know what years the Taco came with this double-cardan joint from the factory in the rear driveshaft. I know my 2000 had it, and I think the one Kumar used was from a '99.

Very clean setup, just modifying the length of a great Toyota factory driveshaft...I did this exact thing on my FJ40, took two factory double-cardan FJ60 front driveshafts and put one in the front of my 40 and one in the rear...worked great and clean, no spacers...best thing was the shafts I used were from a 100K+ mile FJ60, so I was going to have the driveshaft shop rebuild the cardan joint, put in new u-joints, etc. After hot-tanking them and inspecting, they said there is no use, they are in perfect shape...and I was willing to pay for it anyway, and they said don't worry about it...yet another reason to use good quality Toyota stuff...

If you want, I think Kumar has some pictures of his driveshaft on his website: http://kumar.fzj80.com

Now, (since this post was about our REAR driveshaft), if anyone find a drop-in replacement for the rear shaft...make it well known PLEASE!

Later..

be careful with Taco double cardans they are not all the same , one of the fronts shafts (not sure witch model/year) has much less angle than most double cardans

 

[MTNRAT]

Our front and rear driveshafts are different. The front has bolt spacing of 2 3/8" and uses 9mm bolts. The rear has 2 5/8" bolt spacing and uses 11mm bolts. This means the the tacos ds which is the 2 3/8" spacing and 9mm bolts cannot be used on our rear flanges. I thought that the later model tacos had a 2 5/8" spacing, but I just measured a 2001 and it was 2 3/8". I am working on an answer as we speak.

What about the CV joint on the front driveshaft of the 88-90 FJ62? If I remember correctly / fairly sure it utilizes the 11 mm bolts?

Will check later today - have one on the rear of the FJ40

I just measured a fj 62 and the spacing is 2 3/8" with 9mm bolts. Cdan told me that the 81-84 FJ60 uses 11 mm bolts. I posted a request on the 60s tech forum for someone to measure theirs. If someone on this board has a 81-84 FJ 60 it would be a real help if you measured yours. WAIT, Big_Moose, you have one of those. Would you be so kind as to measure it.
Thanks,
Sean

Doh, yes the 83FJ60 I have uses 11 mm bolts. I also looked at my FJ40, which has a 81-84 CV [rather then the idiot above mentioning a FJ62 ] joint using 11 mm, since I had to change the studs in the parking brake drum on the rear of the TC.

I can measure the angles later today if you want / need

He's after the mounting flange bolt spacing at the CV end.......

 

[Big_Moose]

Sean & Dan

Ok. The bolt mounting pattern on the 81-84 FJ60 Front CV is 2.678 ~ 2 11/16 ~ 68.0 mm by 2.370 ~ 2 3/8 ~ 60 mm.

These measurements are bolt-center to bolt-center.

Joe

 

[MTNRAT]

Joe. do you mean the bolt pattern is not square? The rear driveshaft of our 80s is 2 5/8"x2 5/8" or 66mm x 66mm, bolt centr to bolt centre. That is the dimension we need. I would expect all driveshaft bolt patterns to be square, not in a rectangular pattern.
Thanks,
Sean

 

[MTNRAT]

OK, I just got confirmation that the double cardan front driveshaft from an 81-84 FJ60 IS 2 5/8" bolt centre to bolt centre and has 11mm bolts. Again the research of Cdan has helped us out once again. This should work on our 80s. It will either have to be lengthened or the double cardan cut off and put on our existing driveshafts. I will post as I get my hands on one of these and go through the process of fitting.
Cheers,
Sean

Hmm...great if that's the case. Those are the shafts I used on my 40 ('81 - '84 FJ60 uses the same bolt pattern as '76 and later FJ40), the actual shafts I used were from a '84 FJ60. That bolt pattern looks to small to me, I'll try to measure tonight.

This is looking up, pretty soon we'll all have double-cardan joints, with insane lifts..

The Toyota CV's / Driveshaft flange bolt patterns are NOT square or 2 5/8" bolt center to bolt center.

I measured again and it is not a square pattern, which is true for all cruiser years up to the FJ62, and 4x4 mini-trucks.

Lets see if these pictures show up

Joe

Here are pictures of the double CV & At max angle

 

[Big_Moose]

Here is a picture of the flange face - notice that the bolt centers are not equal / square

 

[Big_Moose]

Sean

Here is what Dan was explaining hopefully..................PDrum has 11 mm studs [equivalent to TC output flange is function for DS connection], and the diff flange also has the 11 mm holes / pattern........notice the different patterns for the various years / sizes of Drive Shaft flanges
