What is the torque on a pinion nut?

How much does it cost to have a rear differential rebuild?

A typical rear differential repair costs anywhere between $200 and $400. These typical repairs would include your bearing, seals, and fluid changes. Of course, when a gear change is required, that’s when things get pricey. $1,500 is just the minimum you can expect to pay for new gears.

Can you put grease in a gearbox?

Open-gear grease formulations are often highly additized to support extreme loads and temperatures. Some amount of grease can be added to an oil-lubricated gearbox to reduce lubricant leakage or noise. With this in mind, it would be acceptable to use an NLGI #00 grease in the application.

Can you mix gear oil with grease?

For example, gear oil may include a sulfur-phosphorus extreme-pressure (EP) additive. A grease’s thickener is made first, and then oil is added to achieve the desired grade. Therefore, mixing oil and grease will change the ratio of the base oil to the thickener, resulting in a lower consistency grade.

Can you mix oil and grease in wheel bearings?

Mixing grease, though, could be disastrous. As the various thickening agents interact, they might lead to grease hardening or oil dropout. In either case, your bearings, shafts, joints or other moving parts could be left unprotected, open to corrosion, prone to wear or apt to complete failure.

What are the different grades of grease?

Greases are classified into nine consistency grades (000, 00, 0, 1, 2, 3, 4, 5, 6) established by the National Lubrication and Grease Institute (NLGI).

What is NLGI 000 grease?

NLGI 000 grade grease has a semi-fluid consistency similar to cooking oil. Grease consistency is a major contributor (in combination with additive technology, base fluids, and types of thickeners) to the performance of a grease and how well it will execute lubrication tasks in specific applications.

What does NLGI #2 mean?

The most commonly used greases, such as those used in automotive bearings, would use a lubricant that is NLGI grade 2, which has the stiffness of peanut butter. Grades within this range can operate in a higher temperature range and at higher speeds than NLGI grades 000-0.

What is the difference between NLGI 1 and NLGI 2 grease?

There are two basic types of grease for most equipment and machinery applications: NLGI #1 grease and NLGI #2 grease. So what’s the difference? Less thickener makes a #1 grease more tractable and slippery, while #2 grease has more thickener, making it stiffer and great for all-purpose applications.

Why do wheel bearings need NLGI #2 grease?

This grease shall resist oxidation and consistency degradation while protecting the chassis components and universal joints from corrosion and wear even when aqueous contamination and heavily loaded conditions occur. NLGI #2 consistency greases are commonly recommended, but other grades may also be recommended.
