Niveau huile du pont

Faut il ètre à ras du trou de remplissage lors du niveau du pont où bien légèrement en dessous. Il semblerait qu'il faut ètre 1/4 de pouce (6.4 mm) en dessous du trou selon certain forums us ou alors j'ai pas compris.

"The C5 uses a rear :De axle assembly built by Getrag in Germany. It bolts to the back of the transmission and the trans output shaft is splinted directly to the axle's pinion. It does not share lubricant with the transmission. It uses a conventional, hypoid gear set having a 7 5/8th-in. diameter ring gear and a traditional, clutch-type, limited-slip differential. Axle ratios are: base, 2.73:1; optional for automatics, 3.15:1 and for all manuals, 3.42:1.
GM recommends no maintenance fluid changes and, again, if you run your car hard, we suggest you change your fluid every 35,000 miles. Fluid checks are accomplished by removing the axle fill plug. If the level is between the hole threads and a quarter inch below the threads, the axle is full. Replace the plug. If you are going to change the fluid, remove the axle drain plug. When the draining is done, replace the plug and fill the axle through the fill plug hole to the level discussed above. The factory-fill lubricant is mix of GM Axle Lubricant (p/n 12345977), an 80W90, petroleum-based, GL5 gear oil, and GM Axle Lubricant Friction Modifier (p/n 1052358).
Friction Modifier is required to eliminate limited slip noise or chatter and the Service Manual recommends a mix of 6.25% Friction Modifier or about 3.4 ounces of the axle's 1.7 quart, lubricant capacity. The product works by slightly altering limited slip action to reduce chatter. Obviously, for highest performance, we want all the limited slip action we can get, so a better (but admittedly more tedious) way to add Modifier is by trial and error. Fill the axle with lubricant to a quarter inch below the fill hole threads, then add two ounces of Friction Modifier. Warm the axle for ten miles then make a slow-speed, tight circle. If you feel chatter or hear a squealing noise from the rear of the car during the turn, it's probably the limited slip. Add another half-ounce of the Modifier and road test again. If the noise is still present, add another half-ounce and road test. Once you have gotten to the point of no squeal or chatter, if necessary, top off with a little more axle lubricant.
Generally, it will take 2.5-4 oz. of Friction Modifier to solve most noise problems. If you get to 4.5 ounces and the noise persists, there may be a problem with the axle and you need to take the car to the dealer for repairs.
We feel a better axle lubricant, especially if the car is raced, is Red Line 75W80 Lightweight Synthetic Gear Oil. While there is a very slight performance increase in using a synthetic through a reduction in friction, the real advantage is a synthetic's ability to lubricate better at high temperatures. The C5 axle is packaged tightly and flanked by two hot exhaust pipes. Axle cooling, especially on hot days on the autocross or road race track is going to be at a premium. Perhaps a synthetic lubricant is a good choice. Red Line includes 6% friction modifier in their formula so addition of a modifier is usually not necessary. The only exception might be a new or near new axle converted to synthetic lubricant. In that case, a small addition of Red Line's own Friction Modifier might be necessary."
