99 XJ

So I started to go from 4.5 to 6.5 today so I started with the cossmember and when I took it off instead of the trans and t case dropping down some it went up and to the passenger side motor mounts are fine and when I take a jack stand and jack up the driver side of the axel it brings it back down some so that do you guys thing oh and to pit the crossmember back on I have to use two ratchet straps one to pull to the side and one forward anyone ever had this kinda problem please help me asap

Pictures? Can you reword it a little better? I am having trouble understanding what the cross member has to do with a bent front axle.

99 XJ

ok sorry so when you take off the crossmember the trans and case should drop down. right? well it gets pushed up and to the passenger side i was thinking maybe the front axel was bent pushing the driveshaft back pushing the t case up.but when i jack up on the driver side of the front axel while the jeep is on the lift it pulls the t case down some idk if this helps any sorry

AeroSynch

Yea I understand now. Does the axle look bent from the front, under, or on top?

i can see anything just by eye i guess ill figure out when i go to my buddys shop to do a alinement on it

your DS wouldnt be pushing the entire engine/tranny/tcase assembly arround unless its bottomed out or there is no grease on it and its frozen. If its able to compress and extend from where its sitting currently, I highly doubt that the DS is causing it.

So, did you just pull the crossmember without supporting the engine/tranny/tcase at all?

Hoooper

video would be great, at least pics though

Never said it was the ds I said the axel is pushing the ds back and yes it's bottomed out and like I said the crossmember is off so why would other trans and t case move?

Do you have long arms?

Hoooper

the only thing that connect the axle and the engine/tranny/tcase is the DS, how else would the axle moving affect those?. why is the DS bottomed out if youre on a lift, that doesnt make any sense. bottomed out=/fully extended. And now that I think about it, the DS pushing on the tcase (force going out from axle and into tcase) is the only way it could cause that. If the DS was pulling on the tcase, the engine/tranny/tcase would rotate down since the point of force is behind the engine mounts.

I think something else is going on. How much would the axle have to be bent to cause this anyway? If its any sort of significant movement it would have to be bent a boatload, to the point where theres no way it would be driveable

99 XJ

I think it's just cause of the short arm lift for now the control arms are pulling it back into the t case and I thought bottoming out would have been the ds going all the way in

Tankerblade

if you have a short arm lift with a stock DS, there should be no way in hell that the DS would be pushing into t-case

99 XJ

Why is that a short arm would do it first cause it's pulling back on the axel so hard

Tankerblade

Simple test take the driveshaft off and drop the crossmember.

If it does it, then it was the driveshaft. if not, then you have other issues

99 XJ

Spread did that and it came back over so it was the short arms cause the drive shaft is fine
