I have to do a Motor mount Replacement on my 99 Cherokee sport. Im finding that the OEM mounts do not last long, and the brown dog mounts add to vibration issues. Anyone out there have any suggestions? Thanks in advance

 

Brown Dog rubber mounts. I will never buy anything else

 

So i read that with brown dog mounts there was more vibration inside the jeep after new mounts were installed. Do you have a loud vibration inside the cab when driving on street?

Rustys mounts go into my turbocharged builds. Small increase in vibration but nothing rattling or annoying
The engine is locked in place and the mounts are rebuildable.

 

I put some polyurethane inserts in my 01. Stiffer then stock, wont deteriorate with oil and should last a lifetime. I was more then pleased with them.

Brown Dog motor mounts with a polyurethane bushing will cause more vibration in the cab. Choose a rubber bushing when you buy and you wont notice a difference in vibrations from your stock mounts.

 

If you have a transfer case drop...the rubber brown dog mounts shift because the engine tilts back and the softer rubber flexes more than the poly.
