Lately, I've heard a noise that is getting worse coming from the front of my 95 disco. At highway speed, if I turn to the left slightly, I get a hum or buzz. Going straight, no buzz. I also hear a tick-tick at slow speeds. Two guys say wheel bearing. I know nothing about this part of my truck. Anything related to CV joints? Thanks as always. James | ||

Wheelbearings and CV joints are completely different. http://www.spanishtrailrovers.com/Tech/Maintain/Wheel_Bearing_Replacement/wheel_ bearing_replacement.html -P | ||

Thanks for the info. What are the first signs that the bearings need to be replaced? | ||

The bearings on the Rover are so robust that they should not need replacement under usual conditions. I have heard of folks running original front bearings for more than 300K miles. These bearings are the same as used on Dodge trucks and John Deere tractors! That said, I know of folks who have replaced them every 40K miles, but I think their dealer saw them coming! As for how to detect imminent failure, heat is the first indication a bearing is going away. In most cases with a Rover, this isn't a reliable indicator as most Rover rims obscure the hub from your reaching out and touching the hub to check for elevated temps. While usually CV joints don't make noise at higher speeds unless they are in really bad shape, the tick-tick could be indicative of a bad CV. Go into a parking lot and turn the wheel to full lock and gently drive it in circles. If it binds or clicks, drive it home and tear it apart before it explodes. Sometimes, you can tell the CV isgoing by the amount of play at the drive flange-if the CV joint stub moves out of the drive flange, you're in bad shape. I once worked on one where you could pull the stub in and out 1/4". Depending upon local weather conditions, it might be advisabe to open up the hub and pull the bearings/CVs and at the very least, repack the bearings and inspect the CVs. D'Oh, do you know your swivel fluid level? This should be your first step as if you find low or no oil, you can probably assume it is the CV rather than the bearings. I know it sounds as though I am the worst doom and gloomer there is when it comes to CV joints, but you only need to see one explode and tear up the inside of a swivel ball to feel as I do. The sad thing is that the vast majority of CV failure are due to lack of oil in the swivel balls. This truly is sad as it is something that is so easily controlled and prevented. Paul | ||

The wheel bearings, when worn, make a grinding feel when cornering, and it gets progressively worse and worse till you replace them. IMHO its fairly obvious when it is them. When you change them though, ahhhhh, its like floating on air! Dean | ||

Paul, thanks for all that. My truck has 177,000 miles and I just upgrade as it breaks. CV's are next on my list. I'll check the swivel oil. They aren't leaking but could be dry. |
