Dana 30 or Dana 44
Dana 30 , 27 spline – reccomend tires no bigger than 33′s ? Dana 44 , 30 spline I have a 97 sonoma , 4.3 , 5 speed , running 35×12.5′s now . But want to do solid axle swap. Some trailing,mud,rock- but is my daily driver . gears are going to be 4:56 . I can get a set of Dana 30′s , but should i go with the Dana 44 ? I will probley go from 35′s to 39.5′s . so the dana 44 would be the smarter way to go ? next would be weight 30 vs 44 ? you can rebuild a 30 to be almost a 44 , but then would you just keep brakein axles ? I know just thinking about weight for V6 , S-10 body style , will do chip later

Air Intake Water and engines do not mix very well, and when they do it almost always results in bent pistons, valves and crankshaft commonly called �hydro-locking�. If you think this sounds expensive you're right. The positioning of the air intake is critical to how well a vehicle can handle a crossing. For example certain Toyota models have their air intake directly behind the headlight, which is great to allow cold air into the engine but unfortunately is equally as great in directing water into the engine (An easy fix for this is to remove the plastic tubing from the air cleaner to the headlight when crossing water). NEVER attempt a water crossing where the water depth is above the air intake height. If you intend doing regular water crossings, its a good idea to fit a snorkel as it raises the air intake to your roof line. It doesn't mean you can use your 4x4 as a submarine!
