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.

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 reason i dont want to add weight is because i weigh 160 and the weakest point on my system has a safe working load of 125 (the pulley)

Yes, I would like to see these systems as well, I'm working crosses a lot more and I rarely have a spotter, I was thinking about making a simple but cheesy pulley system.

I made a pulley system for my rings where I wear a belt and a length of cord is attached to either side of the belt runs up through some pulleys and I just hang some weights from it. Whatevr weight I hang on it is the amount of assistance it gives me. So it can be as little as 1 lb or say 50 lbs. At the moment I can hold an iron cross static hold with 20 lbs of assistance. My bodyweight is 150 lbs so if I weighed 130 lbs I'd be able to hold the cross without any help. The pulleys are a great help and it keeps the movement feeling very natural. The pulleys also helped me work up to full bodyweight cross pullouts and bodyweight rings turned out dips.

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?

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 Chevrolet. Simply tell us the year, model and style of your Chevrolet and we’ll show you a fair price for the repair.

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.

Here's a couple of sketches of how I set up my simple pulley system. My rings hang from the rafters in my garage so it's easy to rig up something like this. You just use the rings as normal and whatever weight you add to the pulley system makes you lighter by that exact amount. I tested it by standing on bathroom scales and it's very precise. If you add 20lbs to the pulleys then you weigh 20lbs less so for static holds you can gauge improvements by very precise amounts. I use a thin nylon cord to run through the pulleys and it has a breaking strain of around 300lbs and as I only use around 20lbs on the pulleys it's more than strong enough. For the pulleys I use solid metal ones which were very cheap on ebay. First time round I used metal pulleys that had plastic wheels but they broke after a few months of use so go fo all metal ones. I use two pulleys each side to keep the weights far enough away from me that they don't interfere with any exercises.

someone who is good with physics or pulley mechanics know a way to decrease my assisted leverage without increasing any weight?

I think what you are thinking of is where you have something called compound pulleys where they are mounted one below the other and this is different to having them set at the same height as I have. It's only the height difference that changes how they affect the weight. Look up compound pulleys on google to see what I mean.

that diagram helps i'll try a similar that setup today, btw i use a long heavy duty velcro strap as a belt and it works pretty well

On the diagram, you use 2 wheel pulleys. The more pulleys you use, the less the weigh will weigh because it will have more resistance. Is there any reason you would not just use one? perhaps not enough room in the space? I would figure one pulley in the center of where 2 are placed in the diagram would be perfect and you still would not interact with the weights. I am not sure how much of a difference, but I am pretty sure the weight will feel different.

Recalls may not affect every vehicle of the same year, make and model. Use your VIN or plate to find out if your specific car has open recalls.

The pulleys in my diagram will have no effect on the weight because they are in a continuous train. I tested this also just to make sure with some scales that I stood on. Whatever weight was on the end of the pulleys was the weight difference that showed up on the scales.

In theory, wheel bearings could last as long as your Chevrolet. 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.

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

I don't have a fancy belt/harness. All I did was make 2 loops from 2" nylon webbing and each loop is big enough to go over one leg. Tie one loop to the end of one cord and the other loop to the other cord. See second sketch. It's no good if you want to spin upside down, for that you would need a special harness belt but for crosses, dips, planches etc it works fine.

i was thinking instead of attaching the end to a belt, i'd attached each end to my arm and the closer it is to my body the easier it would be, similar to that iron cross trainer posted here a while ago.

This is not me, is my nephew, simply moving the strap near the elbow decreses the leverage. In that way i can do a cross pull. Of course if you put it as in the video (about elbow height) you loose the elbow training but you can gradually move the straps far from the elbows. Although the pressure on the forearm is very intense and cuts the pass of blood easily, so is better to put a protection between the straps and the forearm.
