CAMOBRAT Posted April 15, 2005 Share Posted April 15, 2005 Anytime I let off the gas in my 85 BRAT without applying the clutch, I get a loud thud and jolt in the entire vehicle. The thud sounds like the engine just fell out into the road. The same thing happens when I hit the gas hard in low gear. I can control it if I use the clutch to make sure the engine and tranny are at the same speed before I let off. Anyone got any idea?

But it sounds like a classic case of a broken transmission or motor mount. Link to comment Share on other sites More sharing options...
CAMOBRAT Posted April 15, 2005 Author Share Posted April 15, 2005 I checked the motor mounts. I was told that I had a loose one. when I attempted to jeck the motor; the entire car was moved. I checked the bushings and found no problem. I did find a problem with the transmission mount on the drivers side. All the bushing was gone. I will repair thi today. We'll see. Any idea how to tell if a motor mount is bad other than jack up the motor and see if it moves? CAMOBRAT Link to comment Share on other sites More sharing options...

heep70 Posted April 16, 2005 Share Posted April 16, 2005 I am also interested in the results of this thread. I also have the same noise in my 86 wagon and have checked the mounts to find them good. I have also noticed the noise is more frequint when it rains. Guess which state I live in.:-\ Link to comment Share on other sites More sharing options...
Mykeys Toy Posted April 16, 2005 Share Posted April 16, 2005 I forgot what you call it but check the rod that bolts under the spare tire to the engine block it can make that noise when accel and decel. Mine did. Link to comment Share on other sites More sharing options...
4x4mudrat Posted April 16, 2005 Share Posted April 16, 2005 EJ20 conversion = no pitch stabilizer. Looks like my mounts are all good too. Link to comment Share on other sites More sharing options...
4x4mudrat Posted April 17, 2005 Share Posted April 17, 2005 That's what the problem is though. Lack of Engine Pitch Stabilizer. Problem solved. Link to comment Share on other sites More sharing options...
torxxx Posted April 18, 2005 Share Posted April 18, 2005 all I do to check the engine mounts is open the hood all the way up, lean it against the wind shield.. grab the alt bracket and the oil fill neck and shake the @#%^ out of the motor. it shouldnt move but a 1/8 inch with the mount bolts tight Link to comment Share on other sites More sharing options...
