so i put a wrench on my xj and took out the hp30 out of the front end. all the perches and control arms lined right up. it took me 3 hours took complete by myself. took it out of xj, unistalled the dana 30 out of the tj and reinstalled the hp30 in the tj. one thing i forgot because i was so dam excited and wanted to get it in asap is the gearing. my jeep isn't driviable right now. the gearing is different and i don't want to mess anything up. i'm going to trailer it to the shop tues. morning. i didn't swap my 35 for a 44 like i intended, instead i went to the yard and pulled it out yesterday with a friend of mine. i ended up paying $400 and it has rear discs. my birthday is coming soon so i'm asking my wife for a front axle kit for the 30 and then i'll have to figure out the gearing issues. i know i will need new gears front and rear.
does anyone have a gearing chart? i use my jeep as a dd, but it is also a everyday warrior. if i see something i want to try i just do it. i'm thinkg 4.10's, but if anyone knows what would be better let me know. i never take my jeep on the hwy and i rarely drive more than 45mph. most of the time i just putt around. (i don't work, hate me if you must).
i'm thinking right now for my better interest would be to reinstall the 30 in the tj and wait till i get the axle kit and have a chance to re-gear both diffs. (then i can sneak them off to the powder coaters too) i would be able to rebuild both axles as well.
what would be a good build up on these?
front is a dana hp30 and rear would be a dana 44.
i want to do alloys and seals, bearings, lockers.
think budget please. i already have the axle housings.
budget is $2500 for both. this is breaking my bank but of course i want it done right. i don't like going back to fix things i stimped on. i like to do it right the first time around.
if i take on a short trip about 12 miles, how bad will it mess things up. i don't know what gears i have in either diff but i can tell you when i drive it something just isn't right. been around the block twice, but my block is about 3 miles. hope i didn't already do the damage.
i had put it in four wheel for about 100 yards and it seem like it was surging a little. i then disengaged it and all seemed to be fine. i only put it in four high. 4.56's sound right for me. thanks for the heads up.
i ordered a two rebuild kits from quadratec. the kits that include the seals, gaskets, crush sleeves, and bearings. my mechanic told me about ten minutes ago he can get me a set of 4.88's for around $300. (does that sound good for a set of gears?) i have the carriers and pinions still. i plan on putting some sort of lockers in there and some sort of alloy axles. besides that, it's just gonna take me some more time. i spent my money for my sye on the dana 44 and rebuild kits. going to run the drop transfer case for now. i should be able to purchase my slip yoke in march or april, and the axles are going to have to wait till june or july before they are completed.
what is going to be the difference between the 4.88's and 4.56's? is my gas mileage gonna crap the bed? (not that i really care?) i drive about 150 miles a week, if that. so mpg isn't a real big concern but it is nice to know. i will be running 33's.
You will want to go with 4.56 for 33s and that would be ok even on the occasions that you have the 35s on.I wouldn't go with 4.88 just to run 35s every now and then and 33s most of the time because that will drop your MPG due to the fact it would be like running a 5 speed in 4th gear at 70MPH down the highway and never shifting into 5th.And actually with the 4.56 gears and 33s you should notice a slight increase in MPG.What is yours now,3.73s???
i have no clue as to what gearing i have. i bought it as a stock 2002 wrangler sport w/ auto. dana 30 & 35. i have since switched the 30 back in so i could get around. my wife won't let me drive my rubi do to the stipulation i told her i bought it for her. i now watch what i say around her, but i can do whatever i want to my tj and she's just says it's your jeep do what you want.
again thanks for all the info. i'll be down the garage for the next 2 days and i'll speak with my mechanic about the axles. my jeep has got to go back in, in a month or two for the sye install, if i can piece together an axle build up using used parts i might be able to get them in at the same time.
