So I have an opportunity to buy a reverse rotation d60, and I have an HD d60 rear axle. So I was wondering if there is any reason I cant press the tubes out of the rr and press the tubes out of the hd and make the hd pumpkin into a straight cut front housing using the tubes from the rr and make the rr pumpkin into a centered rear rr housing. I figure with gears and custom rear shafts I would have about $2000.00 into a pair of d60s. Anything wrong with that idea?

I think the only real question here is "Can a rear housing be used as a front one?" I can cut a spring perch into the housing so that is no problem.

You will want to see if the tubes are the same size. The rear housing will need a washer or something tackwelded into the tubes for a seal seat, and you will want to take the seals out of the ft. housing for use in the rear.

sounds like a lot of work that could potentially cause lots of problems and won't really give a huge benefit. Plus, aren't RRs only stronger in the front and actually weaker in the rear? I seem to remember something like that.

You are correct but since I am sure this is going in his new project YJ then the optimal place for a RC is in the rear because of the driveline angle and YJs dont weigh that much to really matter if there is a RC or SC in the front or rear...JMHO :D

I say go for it...I dont forsee any problems since it would be like putting a regular SC 60in the front but with the correct side drop:D:D:D

There won't be a leaf spring pad on the housing if you use a rear diff for the front. This only matters if you have leaf springs.

I personally would keep the standard cut rear and RC the front. I have had a 9" and a D70 in the back of my YJ and never had a driveline problem that I couldnt work around. The front has had a standard cut 44 and a standard cut 60. both are giving me some problems with the joints maxing out at full travel. I would rather have the RC in the front.

Besides thats a lot of work! :D

If you want a drivers side front 60 that is standard rotation, I'll just sell you one.

per peterson's the hi pinion 60 only gains you 2 1/4" of height

not enough for the cost, trouble in my opinion

are u English or RETARDED!!!.. after u do this, now your rr 60 housing is turning on the COAST side of the gears when you're driving forward.. not to mention your nice new front hd 60 is ALSO turning on the COAST side of the gears when going forward.. driving on the COAST side is WEAK when compared to driving on the DRIVE side of the gears.. keep the rear axle in the rear and rr axle in the front.. you will be much happier.. not to be harsh, but come on now! what ever probs your trying to fix u need to fix another way..

So what? I would put a RC60 in the rear of a short wheel base vehicle anytime just for the drive line clearance and u-joint angles. This is not an issue in longer wheel base rigs, but it really matters for a shorty. Who cares if you are driving on the coast side of a 60. They should be able to handle it and they have handled it. Sure they are weaker in theory, but by how much? I don't see any problems for a rock crawler. Maybe a different story for a mud slinger?

I would say it makes them much weaker, ESPECIALLY in a rock crawler. When climbing at an extreme angle almost all the the trucks weight is on the rear axle. I say this is a bad idea. Sure the truck doesn't weigh that much, but why take the risk and build a weaker rig. What *I* would do is just gain the extra couple of inches in driveline angle by moving the axle backwards, not the pinion up. That way you have a better driveline angle and a rig that climbs a tad better, but again, JMHO...

This is done all the time guys...any hi pinion rear axle is running backwards, and any chevy or dodge front is running backwards.

Having a RC 60 rear and a SC 60 front is running on the wrong side of the gears but they are HUGE gears. Now if this discussion was about RC 44 rear I would have to say no.

Lets get back to the original question.

that's why it's not real good.. i just wouldn't wanna be turnin on the coast side of gears.. dana 60 or not.. ALL front axles turn on the coast side EXCEPT hi pinions.. but fronts tend to see a little less stress... i say fix the prob another way and run 'em the way they're strongest..

There is compromise in everything, If it fixes a driveshaft angle related weakness it might be best thing to do,,,, it's a decision the builder has to make...
D-60 fronts in chevy and dodge trucks have taken a little abuse in the past.

I would like some suggestions and comments on all teralow 60r axles then since what you are saying is this is the weakest way. Or I would like a few suggestions on how to shorten the pinion on a ff 14bolt(in the rear of the yj now) since I have a 100in. wb and am sticking with leaf springs. I have 7 leaf cher chief fronts at all 4 corners and am running a 355sbc, th400,d20 and dont want to have to run a cv d-line. If I do the rr60 in the rear w/ 4.56 spicer gearset and 35 spline flanged shafts I can fit 38.5s easy now and have the option to go taller. If I keep the 14bolt I am now maxed on height and am no stronger than a rr60 since my u-joints will break. Any suggestions without making it 105 to 110in wb would be appreciated.Besides I can have this all done for less than 2000.00 with new 35spline axles and purchasing the d60 front. That is pretty cheap to have that setup done for me. Alot of professional rockcrawling teams are running rrd60s in the rear and have several seasons on them, including anyone with a teralow 60r or dynatracs equivilant.

I would still run a RC60 in the rear just for drive line clearance. How many on this board run RC60s in the rear and have grenaded them? I know Lance has beat the crap out of his and it has held up just fine. I am sure there are others on this board that have had them in the rear as well with no problems. I think Mike Knorr is the only one who had a R&P break in his, but I can't remember if that was an installation error or not. It is not like running a RC60 in the rear is equal to a D35C or anything.

The strength of the gears (coast vs drive sides) is not an issue IMO.

The amount of work and the margin for error in swapping tubes in and out of a front housing is the big thing here.

Didn't terra low quit selling their RC housings cause too many people were screwing them up while pressing in the tubes?
Even people with custom made rear housings sometimes have screwed up stuff from the start (there is a thread on a redline dana 60 in the general 4x4 section on this subject...also I remember that Fearme from the snort club had a major problem with a custom 60 rear end he had built by a "professional").

Wheelinjps rig is pretty tall and I'm pretty sure his rear driveline is going to be at a steeper angle than mine. (if I hadn't lowered the t-case and pointed up the Dana 60 pinion I would have had an angle of 34 degrees on a 24" driveline:eek: )
BTW We both have the same leaf springs on our rigs...but mine is a cruiser with sm465 np205 dana 60 and his is a YJ with a th400 dana 20 with a 14 bolt FF (soon maybe a RC 60).

SM420, shorten the entire drivetrain up. The TH400 is a monster. Then you have a nice angle and a sweet tranny with silly low gears. That's my vote :rasta: but I realize you probably have no desire to do that. BTW, why do you not what to run a CV shaft?

I dont want to run a cv d-line simply because if I have to run one now then if I decide to go bigger I have to sh-tcan it and get a rr60 rear anyway, so I will put the 500 it will cost into doing it once with a rr60. Then if I need one with the 1/4 eliptical and the 42s I'll buy one then.

easy there mr retarded english man...... :D yes it is known to be weaker, but has been done ALOT and the 60 will hold up, 35 spline shafts have went before the r&p has.....
