  Q: How to check for wear in the front wheel bearing and hub in the petrol engine on Mercedes-Benz 190E?

  A:

  With the vehicle parked on a level surface, apply the parking brake and select first gear for manual transmission or 'PARK' for automatic transmission. Jack up the front of the vehicle and support it securely on axle stands. Grasp the first front roadwheel at the 12 o'clock and 6 o'clock positions, and try to rock it; very slight free play may be felt, but if the movement is appreciable, further investigation is necessary to determine the source. Continue rocking the wheel while an assistant depresses the footbrake; if the movement is now eliminated or significantly reduced, it is likely that the wheel bearings are at fault. If the free play is still evident with the footbrake depressed, then there is wear in the suspension joints or mountings. Now grasp the wheel at the 9 o'clock and 3 o'clock positions, and try to rock it as before; any movement felt may again be caused by wear in the wheel bearings or the steering track-rod balljoints, with visual movement being obvious if the inner or outer balljoint is worn. Repeat the operation at the other front road wheel to check if the wheel bearings need adjustment.

  Q: What tools and steps are required to dismantle and rebuild the assembly of the rear hub carrier's Wheel Bearing on Mercedes-Benz 190E?

  A:

  Dismantling and rebuilding the assembly requires a press and appropriate tubular spacers, which are not always available; however, a large bench vice and a substitute spacer such as large sockets can be used. The inner races will be tight on the hub flange, and should the inner race not be detached when pressed out, a knife-edged bearing puller will be required to remove the race. The first step is to take off the rear hub carrier and then firmly hold it in place and carefully press the hub flange out of the wheel bearing center. When the inside race remains on the flange, a knife-edge bearing puller may be used to take it off. The next step is to remove the wheel bearing retaining circlip of the hub carrier, hold the hub carrier in place, and press the wheel bearing out with an appropriate tubular spacer. Clean the hub carrier well and tip out all the dirt and grease, polish all burrs or raised edges that may hinder reassembly, and replace the circlip in case of doubt about its condition. When reassembling, use a small amount of clean engine oil on the outer race of the wheel bearing so that it can be easy to install. Install the wheel bearing in the hub carrier and press completely in place, ensuring it drops into place squarely with an appropriate tubular spacer that touches the outside race of the bearing only. Bearing: place the wheel bearing and have it properly positioned in the carrier groove of the hub. Last, hold the bearing inner race and fully press the hub flange into the wheel bearing, ensuring that it turns freely and then re-fit the rear carrier of the hub.
