Worn camshaft lobesymptoms

Your camshaft will need to be straight, and without excessive wear. The remanufacturing process usually includes adding metal back to the worn areas through welding, and then regrinding the camshaft back to its original profile. A new timing belt and oil seals are also a good idea when you do this.

Hidden inside your engine is a key mechanical component known as a camshaft. For most drivers who maintain their cars properly and don’t abuse them, there should never be a reason to have to deal with a bad camshaft. But if your camshaft does have a problem, it could mean major engine problems and an expensive repair bill.

As its name suggests, a camshaft is a cylindrical shaft with cams on it. These cams are also called lobes, which protrude from the surface of the shaft at specified intervals along the length of the shaft. The location of each lobe corresponds to the location of one of the engine’s intake or exhaust valves, which regulate the movement of the fuel-air mixture through the cylinders.

Should you notice any of these things happening, pull your car over immediately, and turn off the engine (if it’s still running). Don’t attempt to drive it anywhere. Call your mechanic and have it towed in for repairs.

When everything operates together properly, your engine runs smoothly, responding to your foot on the accelerator, and giving you the exact amount of power that you need at any given moment.

If water, grit, salt or sand get to the bearings, the grease in the hub assembly gets contaminated. This will wear down the bearings, and they will eventually give out.

The function of the camshaft is to precisely actuate “valve lifters” that open and close each of the valves at the appropriate moment, coordinating these valve motions (using a timing belt or chain connected to the crankshaft) with the movement of the pistons in each cylinder, and the firing of the spark plugs.

The short answer is: Not for too long. Having bad wheel bearings can range from inconvenient and unpleasant to downright dangerous.

Your camshaft is central to the correct mechanical operation of your engine. Any problems with your camshaft will be noticeable, and will prevent the car from running properly. Here are some of the symptoms of a bad camshaft:

For a national average across all vehicles, the average cost to replace the wheel bearings (for 1 wheel) is about $350 (including parts and labor). But KBB.com goes deeper than that. Based on analyzing 100s of actual repair orders, we put together the Kelley Blue Book Fair Repair Range to show you what you should expect to pay for this repair for your Nissan. Simply tell us the year, model and style of your Nissan and we’ll show you a fair price for the repair.

In theory, wheel bearings could last as long as your Nissan. Unlike oil changes or tire rotations, there’s no standard maintenance schedule for replacing them. However, wheel bearings can be damaged if you hit a pothole, smack into a curb or bounce over a speed bump too fast.

If you hear noises at the wheels, one explanation might be a need for a wheel bearing replacement at one or more wheels. The noises might be described as rattling, clicking, humming, growling, or squealing. It can be a real symphony of sound if you’re not careful.

Broken camshaft causes

Unless you're an expert, you should definitely entrust this job to a mechanic. A thorough diagnosis of why your camshaft is bad, and what caused it, is essential for making the proper repairs. There are a few different ways that this could go:

A new camshaft is the most expensive option. A remanufactured camshaft will cost less, and remanufacturing your own camshaft (if it's in good enough condition) should be even cheaper, since you're supplying your camshaft to use as the core.

How long can you drive with abadcamshaft

There can be many reasons why your camshaft has gone bad, including worn lobes, worn lifters, bad bearings, or even a broken camshaft. A broken camshaft can have a major impact throughout the top end of your engine, doing serious damage to parts like the crankshaft, cylinder block and head, valves, pistons, and connecting rods.

The camshaft and its bearings have been damaged: This is a much more severe type of damage, requiring that the bearings also be repaired. Replacing the camshaft with a new or reconditioned one and replacing the bearings should resolve the problem. Be sure that the bearings are correctly installed, with the oil passages properly lined up for good lubrication.

If you have bad wheel bearings, you might experience the vehicle pulling to one side, sloppy or loose steering, grinding and rattling noises, and uneven tire wear.

More than just noisy or bothersome, bad wheel bearings could also lead to real performance issues like inconsistent braking, spongy steering and handling, uneven tire wear and, in extreme cases, the wheels could fall off. No matter how much (or how little) you know about cars, you don’t want the wheels falling off, right?

The camshaft, bearings, and top end of the engine have been damaged: This is a very bad situation. There is not only damage to the camshaft and its bearings, but other moving parts have also been maimed. This can include the valves, the connecting rods, the pistons and even the cylinder head or engine block. The amount of damage can “total” your engine, and possibly your entire car. Depending on your car’s remaining value, you may consider a replacement engine. If your car is not worth much, is very old, or has a lot of miles on it, this could be the end of the line. Next stop, the junkyard.

Depending on the exact design of your car’s engine, you may have one, two, or even four camshafts. Some camshafts will operate both the intake and exhaust valves, while others will operate only one type or the other. Most camshafts are cast out of iron, but some high-performance versions are machined from billet steel for extra strength and durability. Camshafts run in bearings that are pressure-fed with oil, to lubricate them and remove excess heat.
