checking oil level for font hubs

Motorhome05 · 05-04-2008, 05:36 PM

We have an 05 Vectra gd 36 on an evolution chassis. Was wondering how to check the oil level for the front hubs (tires). Any help? DH took the cap off the right front tire, but could not locate any place to check oil level.

There should be some lines or markers molded into the plastic window portion of the cap. The line approximately 1/4" below the rubber plug/cap is the full mark.

The hardest part is to get the wheel cover off.
Fleetman has it right. in the center is the hup with a line on it and a rubber plug. Fill till the oil is level with the plug opening the line is the minimum level. If you ever have a leaking seal(oil on the tire) the first thing to do is get the cover off and don't move the coach till you have filled the resevoir. Good Luck

Thanks for your answers, however, the cover on the hub is not plastic, it is metal and DH cannot see through it. It has 4 bolts holding it in place. So, before he takes the bolts off, he is wondering if doing so would cause the oil to escape.

No, the metal thing is the wheel cover. It must be removed before you can see the hub. The oil will not escape. Good Luck

The Vectra & Horizon with the independant front suspension have wheel bearings that are lubed with grease. These need to be regreased periodically, so there are no oil levels present to be checked.
