Topic: Regearing dana 30 and 8.8

[enginethatcould]

When it comes to axle I'm lost like a goose in the fog. I have a 93 2.5L with 4.10 gears. I'm currently set up on a dana 30 front and dana 35 rear. I plan on getting a ford 8.8 within the nxt month. I would like to run 35" tires but run 33" now. I will be installing a NV 3550 in two weeks. My question are;

1) What ratio should I be running?

2) What all do I need, besides the ring and pinion? Also, where is the best place to get these items?

TIA

Well, 4.88 will be your limit with the D-30 (don't know what the limit on the 8.8 is).  I run 4.88's with 33.10.50's and it's ok but could be better.  I am piecing together a front D-44 to match my rear D-44 so that I can go 5.38.  The 4.88 aren't quiet enough on steep hills in 4hi and 4low was to low (even prior to the tera 4:1).  You'll need to get an istall kit too (bearings, shims and seals).  Your D-30 carrier will work but don't know about the 8.8.

Can you buy a carrier for the D30 that would be able to hold a higher gear like 5.13?

I dont know of anyone making any gears higher than 4.88 for the D30, and your current carrier would be the right one for 4.88...

No, your stuck at 4.88.

Well...alright...scratch those plans. What would be a good axle that can hold 5.13?

D44's have 5.13 and do OK with 35's...  Not sure on the gears of the 8.8.

Yukon Gear has 5.13 gears for the 8.8. check out www.completeoffroad.com

5.38 is a great gear for the 2.5 and 5spd and 35" tires.  Don't be stuck on an 8.8, d44 rear is a good option. Isuzu Rodeo d44 rear has disc brakes and 6lug to match Waggy d44 front.

What years would i need to look for d44's out of a rodeo and waggy?

[Bounty Hunter]

Early to mid 90's Rodeo, and newer model waggy's have DS diff.

Will I have to modify them much?

Also, what do you mean "newer waggy"

The Wagoneer switched from pass. side diff to driver's side sometime around 1980.

Both are great axles.  I used 1" spacers on my 'Zu rear d44 to get more width, to match the Waggy front.  I'll post some pics of my setup.
