Stay away from the 28 spline 9" axles if you are wanting to use the shafts and carrier. 78-79 bronco and F150 (Not F100) axles are easy to find and a good choice.

sweeeet now all i have to do is find this 9 inch and i will be set thank u for clarifying this cause these axels are all over the place but i never know what to look for so more than 28 spline is good any other things to look for ??

No, the offset may cause problems for you..

My 79 is a 31 spline.

The 78-79 axles will be 31 spline (as long as it isn't a F100) and have the big wheel bearings.

But...
If you are wanting to run 9" of lift (per PM), the 9" has a very low pinion, and may cause driveshaft angle (CV joint at T-case maxed out) and pinion oiling problems at that lift height.

okay i can tame it down to 7.5 but thats about it with my bush whacker flares and 37 inch tires , is there anything else that i should be lookin for maybee a 9 inch isnt for me , but i am willing to work with u felahs , and to add the 78/79 f 150 trucks are the only vehicles with the good 9 inch in them ?? and where can a guy find a high pinion rear axel??sorry i am babeling but i am wanting to get an ideah of what i need then i can start hunting thanks fellahs

There are other ford 9" axles out there, but the 78-79 F150s are the most common.

If you stay at 7.5" of lift, and the 8.8 is working at that height (driveshaft doesn't bind up, and pinion bearing isn't making noise due to excessive pinion angle and lack of lubrication) then a 9" should work as it isn't too much lower than the 8.8.

A semi float dana 60 (full float if you are going to 8 lug wheels) has a higher pinion than both the 8.8 and 9, and may be a good option, but is harder to find.

A high pinion axle would have to be made from a ford front dana 44 or 60 that has been re-tubed, or a 9" with a currie or truhi9 center section.

Yes the 9.25 does have c-clips. I may have also found a 78 9 inch so u think it just be better to use it or the 9.25?

 

[ranger125]

lol i am being hi jacked lol mehh i aint worried hehe but what is the differnce between the 9 inch pibion length some are long some have gaurds like i am not sure which one to use and do u guys think this inverted t steering and 9 inch will work with 7.5 inches of lift??

 

[ranger125]

bump lol i went to the scrap yard today and seen alot of then and i can get one for 100 canadian lol ,but yeah i noticed the pinion length to be different so i am not sure what one to get what should i look for guys ??

 

[ranger125]
