Anyone have a clue. It feels like its lagging power but if I put it in neutral it revs up fine just does it in gear

 

bad u joint or bad drive shaft is what it sounds like to me

 

like stated above it could be a bad u joint. do you have a lift? if so you may need a SYE to get rid of vibs since the angles would be all messed up.

 

driveshaft out of balance? bent driveshaft as well. seen it happen on stock jeeps. Its only felt under load because the driveshaft is bent (weakened) which causes it to flex under tension(on the throttle)

 

Ya my friends drive line did that.
that could be the problem

 

Oh k well the.front Bastard joint/ cv. Thing on the front driveshaft the ujoints do have some play in it and the rear driveshaft u joints are. Brand new. Front axle joints are new new pinion bearings and seals at is like a dadadada n it makes the motor feel laggy its real bad at a stop light or sign on take off it does have a lift 4 inch in front 2 n half in rear on 32 inch tires no trackbar upgrade yet new coil new starter new brakes n rigors I'm stunnedc buddy told me a motor mount but idk

 

try leveling out the back with the front to see if that fixes the problem.

 

That hurt my brain to read.

It could also be caused by a bad motor mount/transmission mount. Definitely check those too.

 

X2. i need to replace my trans mount since im starting to get some slight shaking from that area

 

I apologize

 

Would that have anything to do with it

 

I'd start with replacing those front driveshaft ujoints before anything else since you have play in them. That may very well fix your entire problem right there.

 

A little back and fourth play like up and dwn

 

happened to me when i have to drive around for a week with 6 in lift in front and 3in in back. once i leveled the rear problems went away

 

So I guess fabrication of blocks for now
