The only dana 44 that would fit in the front of an MJ without EXTENSIVE modifications is a Rubi D44, which isnt really a D44, and you won't find one of those at a JY
The axle in my stepdad's one ton chevy was I believe a Dana 70U, it was huge and full floating anyway, and definitely not a Chevy, it was a dually though
I'm sorry, but this is just untrue. Every engine has a specific break in cycle at the factory, the break in procedures after the vehicle is recieved are no more, but they are definitely broken in
Well no, I know that they roll in and out of a dealership with synthetics, but for the engine break in at the factory I believe dino oils are still the standard
Yeah, except there definitely IS a break in period on a 4.0... And as I am not an expert on new industry practices I can't argue the point of 2010 engines, but I have doubts
Could be a coincidence, but when I just bought my dak, I had no leaks, but with Mobil 1 I suddenly had front crank and RMS leaks, its not the only case, this "myth" has some traction
The leaks arent caused by the synthetics directly, sludge buildup around leaky seals will stop a leak, but a synthetic may break it down, exposing a leaky seal
Lastly, I never run any sort of additive. All oil manufacturers do not recomend it, all additives that are aggressive enough to do something (most arent) can have unintended consequences
Firstly, you should NEVER break in new rings with synthetic, secondly the only actual issue with synthetics in old engines is it will cause them to leak, cause they will break down sludge around seals
...Well... The XJ should have 3.07s too, although it is possible that it doesn't... Only way to find out is to crawl under and check tags and/or count teeth
Autolites? NOOOOOO, I won't run those in my mower, heard way too many horror stories. Id run champion coppers only in my Jeep motor. Platinum plugs+blowby=very bad
You most likely have 3.07 gearing.... Which in one word, SUCKS... It is geared way too high, and with my with 3.07s and 31ish tires I have to downshift at the slightest upgrade on the highway
