2008 Cadillac Escalade ESV Ball Joint

You can set the front wheels in the straight-ahead position, install anti-rotation pin J 42640 in the steering column lower access, remove the engine shield, mark the relationships of the Steering Shaft coupling, the upper intermediate steering shaft, and the power steering gear, remove the steering shaft coupling bolt at the steering gear, the steering shaft coupling nut and bolt, the steering shaft coupling from the vehicle.

The power Brake Booster may appear wet due to excessive assembly fluid during manufacturing or brake fluid that could have been spilled during system fill. To prevent unnecessary replacement of the power steering boosters, perform the following power brake booster leak inspection before replacing the power brake booster. To properly diagnose a leak condition, aid from an assistant may be required. The power brake booster system must be observed while completing this inspection. Do not hold the wheel for more than three seconds at a full stop, as this will increase the fluid temperature in the pump above the operating temperature. On low mileage vehicles, at the joint between the power brake booster housing and end cap 1, light moisture is acceptable. If fluid droplets develop, the power brake booster must be replaced. A leak between the power steering brake booster 2 and the master cylinder is not acceptable. If a leak is present, the type of fluid must be determined. The power steering fluid indicates that the power brake booster needs to be replaced. Brake fluid indicates an issue with the brake master cylinder.

When adding fluid to the Brake Master Cylinder reservoir, use only Delco Supreme 11(R), GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container. The use of any type of fluid other than the recommended type of brake fluid may cause contamination which could result in damage to the internal rubber seals and/or rubber linings of hydraulic brake system components.
