hyperion Posted February 5, 2008 Share Posted February 5, 2008 Sometimes when i pull up. I hear a loud short bang on the back side of the car, like the coupling takes the drive axle suddenly. Does anyone know if this is normal or if this is a problem I have to look after. I heard there is a speed difference between the front and the rear drive. Could this cause the problem?

BogMonster Posted February 5, 2008 Share Posted February 5, 2008 Maybe a sign of CV troubles, or maybe even a CV joint gone completely and occasionally grabbing - the Freelander will drive in 2WD quite happily! Quote Link to comment Share on other sites More sharing options...
hyperion Posted February 5, 2008 Author Share Posted February 5, 2008 I will check this. Hope this is not the case however. Quote Link to comment Share on other sites More sharing options...
Blippie Posted February 5, 2008 Share Posted February 5, 2008 Rear diff mount? Cheers Blippie Quote Link to comment Share on other sites More sharing options...
Blippie Posted February 5, 2008 Share Posted February 5, 2008 Mind you, I suggest that the rear diff mount is to blame for virtually every noise people ask about. Cheers Blippie Quote Link to comment Share on other sites More sharing options...
hyperion Posted February 6, 2008 Author Share Posted February 6, 2008 CV looks to be working ok, so no 2WD but 4WD . Rear diff mount, you mean it has to be refastened to the sub frame. I have to check the torque values of the bolts then. Does anyone know those values? Quote Link to comment Share on other sites More sharing options...
Les Henson Posted February 6, 2008 Share Posted February 6, 2008 There are three mountings for the rear diff - one either side by the driveshafts, and one close to the diff nose. I don't have the torque figures I'm afraid. Les. Quote Link to comment Share on other sites More sharing options...
hyperion Posted February 6, 2008 Author Share Posted February 6, 2008 Thanks for pointing out the locations. Perhaps the values are in the RAVE documentation, I will check this. Quote Link to comment Share on other sites More sharing options...

Before getting excited, check that it isn't the exhaust. Some elle cheapo exhausts are poorly shaped, and some are just poorly fitted. This can cause strange hard bangs underneath your car when either accelerating hard or braking. One thing to tgry is accelerate hard in 1st year then remove your foot from the throttle fast. See if ya get a bang from the rapid movement / rock of the engine. Then try to work which section its coming from. Then look for shiney bits.

More along the lines of the rubber bush in the mount wearing. You need to get under the vehicle and waggle the propshaft where it enters the final drive. Too much play means the mount is worn. You can sometimes see how it has disintergrated. Whilst you're under there, move along the propshaft and give it a waggle by the two mounts on either side of the VCU.

hyperion Posted February 6, 2008 Author Share Posted February 6, 2008 Doesn't sound like an exhaust problem, but this is easy to check. I try to see if it is the drive shafts etc. I'll keep you posted on it. Quote Link to comment Share on other sites More sharing options...
