Sitting still in neutral would indicate an engine and/or mount issue. Sitting still in gear would indicate a driveline issue. Of course there are lots of other issues that could cause vibes....

In our experience, a torn transmission mount can transmit lots of vibration. After you change the t-mount, if you still have lots of vibes call us. We'll help you track down the source of the vibes.

 

hey i got the oversized engine brackets and motor mounts but i cant get the drivers side engine bracket to go into place.. there is the something from the fan belt in the way not exactly sure what but its in the way and also the holes dont seem to line up.. at least the holes im trying to use.. does anyone have any ideas of what im doing wrong? did i order the wrong mounts or something? its pissing me off tho

 

Pictures please.

 

If you got the mounts that use a poly bushing instead of rubber then they will transfer vibration more. Its a harder material, there is no fixing it unless you switch back to a rubber bushing.

 

"To minimize vibration, we always recommend changing transmission mount when changing motor mounts. We also strongly urge carefully following instructions. " straight from the brown dog offroad web site

 

love my brown dog mounts on my stroker, wish i knew we got a discount when i ordered mine

 

Night and day difference when i switched my stock motor mounts out for brown dog poly mounts

 

i ended up switching back to stock mounts and all vibrations are gone.
the brown dog mounts i have are rubber and there is nothing wrong with them, bushings are still good. i also changed the trans mount again.(did what the instructions said and replaced it when i put the brown dog ones in )

the cherokee is my dd. i have no carpet, and mt tires. im sure its not just the motor mounts falt but the less rattle/noise i can get in my jeep the better.

i dont mind the slight vibration its all the **** that rattles on my jeep because of it that drives me crazy. if i took the time to track down every piece of plastic that was making noise/ rattling and put in pading or something the brown dogs would be great.

i got these mounts after going thru two sets of stock mm in a few months. at the time i had a tcase drop and i think it was putting a lot of stress on the motor mounts. the brown dog mm held up great but now that i have a sye im gonna try the stock ones again for a while.
