Rear main seal leaking 1995 gmc sierra - 1995 GMC Sierra C1500

SOURCE: low oil when engine warms up gmc sierra 1995

30-40 psi of oil pressure is fine for many vehicles including your GMC. I am assuming that the truck has more than 100,000 miles on it and still has the original engine in it. By rule of thumb you only need 10 psi per 1000 rpms in a typical street driven engine to give adequate oil pressure to keep the bearings from oil starvation. The oil pressure is typically higher when initial start up occurs because it is more viscous due to the temperature of the oil as the engines oil warms up the visconsity thins out and the oil flows more smoothly. The drop in oil pressure is a normal occurance. Above 45 is more than required for a daily driven street engine. I believe that the specs on that engine only list 30- 45 psi.

You are Talking about the Main Cover on the Rear of the Rear end Correct???? If so, This is Just a Gasket and is Very easy to replace. The Gasket is Simply Worn out.

SOURCE: Have a 1995 GMC Sierra Truck. Gas is leaking from

chances are your leaking from the gas line from your fuel tank to engine. More than likely the pressure line, but it could be your return line as well. To figure this out you would need to take your fuel tank off the vehicle, and inspect the lines. look for rust and cracks. Rust is a good sign of weakness, and chances are this is where your leak is. Hopefully this helps.

SOURCE: 2004 gmc sierra rear differential

remove cover.take off back wheels and calipers (or drums).turn differential to where you see small bolt/pin (5/16) horizontally (same direction as axles)on right side of differential.remove bolt/pin.A large pin (about 5"long 3/4"diameter) should slide out differential with ease ( you may have to tap one side of the large pin).turn differential to completely remove large pin.turn differential so you can see in the view window.push each axles in (they'll go in about 1 1/2"each) You may hear one of the axle C-clips fall.If not use a small telescoping magnet to remove the C-clips from the axles through the differential window.pull each axle out about 10"so they are out of the diff.Now remove the cap bolts(4-5/8"bolts) and remove the caps(mark the caps so they go in excactly the way they came out.be careful the diff might fall out.If not you may have to use a long bar or 2x4 to wedge and pry the differential out. Have a basket/crate w/rags in it to catch the diff.TIP:If you are removing the ring gear from the diff, the bolts are left handed bolts meaning you have to turn them clockwise to loosen and counter clockwise to tighten ; )
