Glensts Posted December 20, 2013 Share Posted December 20, 2013 Hey guys, just wondering if someone know the difference between the Mack 46000 diffs and the 44000 diffs. I have the 46's in my 97 Macks and wondering if the 44's are as bulletproof and what experience anyone has had.ThanksGlen Quote Link to comment https://www.bigmacktrucks.com/topic/33951-differential-sizes/ Share on other sites More sharing options...
2stacksuperdog Posted December 20, 2013 Share Posted December 20, 2013 46s are better. they use a cast housing whereas the 44s use a 2 piece housing welded together which ends up cracking and leaking Quote Matt Link to comment https://www.bigmacktrucks.com/topic/33951-differential-sizes/#findComment-222248 Share on other sites More sharing options...
e9500v8 Posted December 20, 2013 Share Posted December 20, 2013 44 are avalible in a cast or fabricated housing. Cast housings are heavier if you are trying to save weight get fabricated. I cannot say one is stronger than the other we have had both and have had no problems.

rsb502 Posted December 22, 2013 Share Posted December 22, 2013 Was told the 44 and 46 were basically the same but with the 46 having the heavier (200 series) carriers standard.

e9500v8 Posted December 26, 2013 Share Posted December 26, 2013 46 is just air ride version of 44. Quote Link to comment https://www.bigmacktrucks.com/topic/33951-differential-sizes/#findComment-223193 Share on other sites More sharing options...
rsb502 Posted December 28, 2013 Share Posted December 28, 2013 46 is just air ride version of 44.I just looked at a spring ride 46 with a cast housing a week ago in a new Granite, the same dealership had fabricated housings on air ride with 200 series carriers as 46 a couple years ago.

Dirtymilkman Posted December 28, 2013 Share Posted December 28, 2013 I believe 84 superdog is right. I have a '96 CL that both housings cracked. They were 44's but ran different size bearings and races. These were also cast. No used ones found in the U.S. had to buy new. That hurt hard.
