I have a 97 GC just bought it a week ago, changed all the brakes, changed diff fluid front and rear, changed TC fluid, basically did a service on it. anyhow when driving (and its random) it starts acting like the brakes are locking up, (making a bit of a popping noise), put the trans in neutral at 70mph made no difference, did the same thing with the TC (put it in neutral at 70) made no difference.... Has anyone had these same problems? p.s. its a 97 5.2 with the fulltime TC..

 

Make sure all your bolts are tight and brakes were done properly. Then maby check your cv joints and then your u-joints.

 

Thanks for the reply always good to recheck everything... figured it out, its the TC, viscosity coupler quadra trac..... never came up against this kinda trouble....

 

well went ahead and rolled the dice, bought a used TC from a salvage 160 buxs. its 2yrs newer then my old one and clean, chains tight, just hope the damn VC is good... LOL
