The remote control/transmitter is nothing special, you can use any rc remote, I use a standard 2.6ghz transmitter / receiver. I mean any rc trasmitter/receiver will do, even from your old rc toys. Just make sure it is legal in your country to use it on an rc aircraft..
Wheel bearing replacement: 2 to 4 hours. ($100 / $300 / $430
Over the past 5,000 miles or so I have heard my front right wheel bearing making a little noise. It hasn’t gotten much worse but it’s best to replace them before they come apart or tear something else up. I have a 1995 Volvo 850.
Proper torque values are:
- Wheel bearing bolts, 33 ft/lbs, then another 60 degrees.
- Brake caliper mounting bolts, 74 ft/lbs.
- Control arm bolts, ball join nut 13 ft/lbs. (plus 120 degrees), subframe bolts 48 ft/lbs. (plus 120 degrees),
- Wheel lug nuts, 80 ft/lbs.
- CV Axle bolt, 89 ft/lbs, then another 60 degrees (36mm or 32mm).
I used a OEM Volvo bearing (so I was told) which I purchased from eBay. I have read that a company named FAG makes bearings for Volvo. They also make the bearings for Timken. Anywho, I would like to think I have a bearing that will last another 227,800+ miles, that’s why I went with Volvo. Unfortunately I have read that someone had an OEM bearing go out on them in less than 15,000 miles. We’ll see (I plan on driving this car for some time).
