95 orvis front end whining

its the whine that u hear when u back up at a high rate of speed, suspecting front axle/drive shaft area. is there a way to make it stop whining or should i just disconnect the drive shaft?

it has a 3" body lift 31s on 15s flow master single to dual and a holly throttle body
5.2 version.. just changed oil used synthetic valvalean with fram filter
miles are 220k on the dot

When does it whine , 1st gear only or constant at higher speeds ? Video might help

NO such thing as a body lift on a Grand Cherokee , it's a unibody .

Fram filters are the bottom of the barrel .

Pic of that TB would be interesting to see , I didn't know they were interchangeable

Probably your differential, but I could be wrong. You should search the forums or google for posts regarding similar issues.

Most likely , pinion bearings . Pretty common issue

Most vehicles whine when you back up at a high rate of speed. The gears are cut/beveled for forward motion and when run in reverse will whine like a "straight cut" gear. Making that noise moving forward is a sign the diff needs rebuilt/replaced, especially if you've been driving it like that a while

BTW you don't have a body lift

good luck with the truck

im new to this lift and i dont know what lift it is, but i do see rubber spacers above the springs they look like 3-4", i have already come to that conclusion and would like to know whats the cheapest method of doing this..
EDIT: i would also need to know exactly what parts i would need

Your requests aren't very clear

Parts to rebuild your differential? Consider looking at a website like Randy's Ring & Pinion and checking out the content of their rebuild kits.
That will give you a good idea what's involved.

Setting up a diff is not a beginner mechanic's job. That doesn't mean you can't learn it, but consider a complete junkyard axle instead
It'll save you hundreds over a rebuild and is actually easier.

The spring spacers are a budget boost lift. The FAQ section is worth an hour of your time.

You might also consider running the truck without the front drive shaft.
A dry U joint can make noises that could be confused with the diff, especially if you have the CV style.

good luck

see i asked before about removing the drive shaft and people tell me that it will have bad problems like the rolling while parked(e-break not working), and or the power not being distributed evenly
if however it doesn't affect the above i would gladly take out the front drive shaft, i would much rather use a junkyard axle like the above post suggests however IM NOT SURE of WHAT PART TO GET, im sorry no one can understand what im trying to say(I got hit in the head 1 too many times lets leave it at that). now i need to know if there are different types of axles and which is the right one for my jeep. i dont want to have to drive 150 miles to harry's u pick it only to by the wrong part on the jeep that i need to fix..the useless Haynes manual is garbage and no useful info can be found there... just general knowledge that everyone already knows..

i did read the FAQs and i dont understand some of them. im one notch below the "beginner mechanic" status. but i am willing to learn.
also worth mentioning that i dont have any tools. just the basic crap
and its leaking alot seen in last pic

i will post picks in a few

Power distribution isn't an issue , not sure where that myth comes from . I ran mine w/o a front shaft with no issues except rolling in park on a slope . Then I fixed my VC and haven't taken it out since .

You have a late model 1995 by looking at the CV style drive shaft so you would need the same style for a bolt up replacement . You also have a 3:73 gear ratio most common in the V8 , not the 4.0 although some did have it too . There are 2 types in our grands , long and short pinions . I can't tell which you have and your year was a change over so because of the CV shaft , I'm thinking short . If you can find a long pinion (u-joint), they are stronger , but grab the front DS also

For the work involved , I would suggest rebuilding so you don't get another bum axle . The kit is like this one but make sure it is specific to your jeep http://www.drivetrainamerica.com/p-1...aring-kit.aspx .

Setting up diffs isn't really something you want to take on . Not saying it's not possible to do , just technical . Check at your local gear shops for a quote , US pricing is not too bad from others I have seen on here .

Hope this helps .

BTW , if you need a free FSM , google it or PM me for a link

rebuilding wont be a problem so long as i don't need any special tools and or don't need to re-calibrate the gears. i would actually like to put in the time and work into it
what is the brand of my axle ? i still need to know it. the kit u linked happens to be on sale and if thats the correct one il order it
