going to 4.11 gear

[lamp210]

Hello
i would like to go to a 4.11 gear in my 75 bronco, now i know for sure that the dana 44 in the front is original and i also know that the rear end is not and i'am not sure what year it is but i do know that it is a big bearing rear end.can i just order the gear sets or do i need to identify anything? front and rear,
thanks.

As long as the rear is a 9in the gear set doesnt matter. But your D44 will either need a new carrier for 4 series gears or you need the "thick" gears that will allow 4 seriers gears to fit a 3 series carrier. Also a good time to replace bearings and seals and you'll also need setup kits for both axles.

yes planned to change all the bearings/seals but can you tell me more about the 3 and 4 series carrier, how will i know what i have do i need to take it apart first?
thanks

What gears do you currently have? If 3.50's you will have a 3 series carrier. 3.90 or lower(higher numerically) then its a 4 series carrier. Doesnt need to be taken apart unless you believe that the gears have been changed before.

what size tires are you planning to run? why the gear switch?

 

[lamp210]

they are 3.50 gears in it now, so would i need the thick gear correct?

Yes you need a different carrier for the 4:10 ..Also on the front there are a couple of seal up inside the axle ..It's been years since I did one .. Maybe it's called and inside tube seal ..If your going to be apart you want to get them all....

your better off just getting the 3.92 and up carrier it seems to be the simplest and prob cheapest choice.


also take the above advice and get a master rebuild kit for both.

 

[broncnaz]

Yes you need the thick gears unless you buy a new carrier.

 

[lamp210]

well it seems to me the way to go would to just pick up the thicker gear.

 

[broncnaz]

I think it would be as well. The price differance is where its at.

 

[lamp210]

i suppose when i order my gears i would specify that i have a 3 series carrier and i need the thicker gear and they should know what talking about?

yes they should know, were are you planning on ordering them from?

 

[broncnaz]

You only order the thick gears because you have a 3 series carrier but yes just make sure they know so there is no confusion.

 

[fordguy]

any of great sponsors/vendors would know what you need.

 

[lamp210]

thanks for the good advice i indeed learned something here thanks.

But now is a good time to decide if you need a locker or limited slip in the front. If you do, get the appropriate locker / diff and get regular gears (as opposed to thick gears.)

((Many lockers replace the current small carrier you have.))

I got the #4 carrier for $60. Thicker gears were close to that. I swpped the #3 carrier for needed parts. I came out better with the new carrier.
