lbesaw Posted January 30, 2008 Share Posted January 30, 2008 Hey guys. I have a 91 ls 400. I recently put a drivers side rear cv axle in it. I had to puul the rear end to reinstall the clip for the halfshaft as it had came out somehow. Now it has a noise similar to driving over a rumble strip on the side of the road to wake you up. This noise happens at random and only for a breif second and then it goes away...anybody have an idea...it never did this before in 217,000 miles Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted January 30, 2008 Share Posted January 30, 2008 Is there any vibration with the noise?? Like the rumble strips? How often?? Quote Link to comment Share on other sites More sharing options...

jcrome04 Posted January 30, 2008 Share Posted January 30, 2008 Are you 100% sure it's installed properly? When was the last time you serviced the differential? Quote Link to comment Share on other sites More sharing options...
lbesaw Posted February 4, 2008 Author Share Posted February 4, 2008 yes i am certain it is installed correctly. I serviced the rear end when i pulled it out to inspect for problems. I found nothin gout of the ordinary... Thanks Quote Link to comment Share on other sites More sharing options...
Leadfoot Posted February 4, 2008 Share Posted February 4, 2008 yes i am certain it is installed correctly. I serviced the rear end when i pulled it out to inspect for problems. I found nothin gout of the ordinary...Thanks Is the duration around a second? Is it at a certain rpm? Under light throttle? My '92 does something similar once in a while, accelerating lightly at 1800 rpm going through 45mph. I have a badly leaking EGR pipe but other than that have not been able to determine what causes it. I cannot repeat it consistantly, which does not make diagnosis easy.

It is very short like you said around a second or less. I can not pinpoint an rpm but under light throttle is correct...very strange Quote Link to comment Share on other sites More sharing options...
