Bicycle Mechanics - Bike Falling Apart!

I have a Fuiji Hybrid that is about 8 years old. I've been putting a ton of miles on it commuting and wondering when is it time to get a new bikes. The past year I've had to replace pedals, bottom bracket & now a rear axle. I feel like it's a used car and am dumping $$$ into it. What are some of the things that I will be looking at in the future to replace??
Thanx

Your used car analogy is very apt. Bike components like car components have finite lives, and those on lower priced bikes aren't expected to stand up to high mileage life. It's impossible to predict what will come next, but not counting tires and brake shoes which normally wear out, expect your chain and cassette, and maybe chainrings to wear out soon. Brake and gear cables also don't tend to last forever so they may come next.

My advice is that you learn some basic bike repair and maintenance to prolong the length of the various components. For example keeping up with basic lubrication of all bearings and the chain to maximize their life expectancy. You also want to know how to replace commonly worn parts like brake shoes, cables, tires, etc. Being able to do your own work will help you keep this bike on the road at low cost, since most of the related cost is for labor vs. the actual replacement parts.

Or you can send it to me :)

OTOH, a new ride might be just the thing to brighten up the OP's day. bk

Based on what you have said my guess is you may need a new cables, chain, and derailer pulleys in the near future.

Thanks everyone. I just got it back from the shop with the new rear axle and the back tire still wobbles a tiny bit. Not sure if I have to adjust the spokes or fuss with the quick release.

Does it wobbles when it spin ? then it need to be trued ( adjusted the spokes ) . if it wobbles when you push the wheel side to side then it need a hub adjustment or as you said fuss with the quick release .

Take the wheel off the bike and remove the quick release and wiggle the axel from side to side. if you can feel any wiggle, take the wheel back to the shop and have them adjust it. I had a rear wheel that I couldn't adjust the bearings on at all. I finally decided to take the whole thing apart and check everything. The problem turned out to be that the free body was loose on the hub. I tightened the free body and adjusted the bearings. You may want to check that, or have the shop check it. If the axel wiggles they did not adjust it properly.

with a quick release there will be a little play (wobble ) to the axle ,outside of the bike , which will go away ,once the the quick release is adjusted right.

There may still be some end-of-season deals right now in stores.

Fussing with the quick release will not fix wobbley wheels! If the wheels wobble it is because hubs are out of adjustment or the wheels are not trued correctly.
