Question:

The designation of the bearing fitted at the rear axle after differential in a Opel Ascona B 1977,1.6?

Does anyone knows which is the bearing that is fitted at the rear axle between the differential and the wheel, from the side of the differential, of a Opel Ascona B 1977, 1.6 litre? It must be ball bearing deep groove with number 531458, but I am not sure. It is also fitted together with a gasket in order not to have a leakage of differential lubricant.

Answer:

Nobody wants to touch this?? Sir, It is simply your wheel bearing if it is located near the wheel. If you have your differential cover off and it is near the little gear on the right or left of the Ring Gear(the biggest one) it is called the Spider Gear and hence the Spider Gear bearing. When discussing Gasket I suspect it to be the Wheel Bearing near the wheel. This requires removing the axle and a puller to remove the bearing from the axle tube. Dirty, never goes right, pain in the **** procedure requiring possible heat application or very carefull cutting of metal. Damage to the axle tube is NOT allowed. Seek help/a good shop to do these. Some of them are pressed onto the axle and can really only be removed and installed by a machine shop with 20-40 ton presses! Don't even mess with them just take the axle in to them. Sounds like you can see the bearing so I think I got the bases covered here. Good Luck ASE Cert Auto Tech, Shop Owner
