Question about 2002 Chevrolet Suburban
My 99 4wd suburban is making a noise when i release the gas pedal...sounds like a grinding noise from the transfer case. transmission shop told me that all is ok....have catalytic converter checked. any ideas?
SOURCE: vibration at 45 mph.
first, if the milage is high it could be a cv halfshaft even if the boots are not split. if the tires are new and no rims are bent, make sure there is no fix -a- flat in the tires, (liquid will not balance) and cause a severe vibration. i would suggest you take it back to your shop and have them put it on a lift, raise up the front wheels under the outer part of the lower control arm where the front is not hanging down too far and start the vehicle. run it up to 45mph to 60mph and have them feel in the drivetrain for vibrations and shakes.if it is felt with the car this way the vibration is in the drivtrain. inner cv's or in the transmission. thanks and let me know what you find out.

there is a cable running from handle to brake assembly it is probably broke there is a release lever under there on brake about a one inch lever hold down on brake and move this and let up on pedal.

you're having the same problem i had with my 99 isuzu rodeo 2 wd 3.2 i paid a muffler guy over $600 to replace those catalytic converters, if you're good at welding you could do the welding yourself after buying the catalytics, basiclly i seen them just cut them off and welded them back on

it's possible you might need to just change the trans case fluid.... it's a pretty simple task, i usually do all the small minor work first before i take it to a dealer to fix.... if they said you need a new trans case, but didn't tell you why, more than likely there might be something you could do yourself to make it better... those service men have been working around vehicles long enough, they should be able to tell you exactly what's wrong!
i would also do a tranny fluid change to... some of the noise could be coming from there too -- when you change either fluid, add a little lucas transmission fluid stabilizer, it helps alot with seals and makes the fluid stick to the gears better...
