Howdy all, im looking at a GQ, petrol4.2 with factory diff lock and swaybar disconnect for Glen (gec) lad.
Can i check the diff locks operation without jacking up, ie listen for a sound of it engaging. And i assume the disconnect will be fairly obvious to see if thats working, but any hints of things to loook for would be good, cheers
To inspect operation of diff-lock without lifting You car up - try like this: find Yourself a piece of clear asphalt road. Should be dry, in level and no dust-sand-rocks at all. Put some sand in front of right rear wheel, not much. Try to foresee the trace of this particular wheel while turning. Than start engine, let underpresure being pumped for 5-10 seconds and switch DIFF-LOCK on. Then turn Your vehicle left and slightly start going. First of all You should hear click-sound and indicator on Your desk. But more important is to observe this sand on the road after Your wheel rolles on it. If protector stamp-trace is visible all the way Your diff-lock is ill. If the trace is clear for 30-50cm and suddenly pulls the sand Your d-l operates correctly. Of course You may do the same with left rear wheel too but it does not matter - must be the same result in both directions.
or just get a wheel off the ground and test it from there
That's just asking for trouble. Best thing to do is try it on a dirt road. -Lock the diff, turn hard one way, drive forward and listen/ feel if a wheel is dragging in the dirt.Quote:
