    X7 Bottom Bracket

    I have noticed that my bottom bracket keeps getting louder and louder. I haven't taken an "external" apart before. Do I replace the whole thing, or just bearings, or what? Does anyone know what I need as far as parts?

    You should be able to replace just the bearings using the Enduro tool or some creative wrenchin.

    If you have a bearing warehouse near you can get the numbers off the bearing seal and they should have them on hand.

    Jill...or dog...

    Is there any way to find out what the exact bearing is before I tear into it so that I dont have to have by bike apart for several days waiting on parts?

    You will most likely have to pop off the left crank arm to see the bearing numbers located on the seal, the manufactures dont include that info on their tech sheets.

    Stock truvative cranks in the stock external BB. Not really sure more than that...lol.

    Since I dont have the proper tools, I might just take it into the bike shop. Depending on cost...

    Here is what my local bike shop has. They have the Truvative Howitzer "Team", and the CrMo. What is the difference? Is the team better than the regular? Or should I just order it online and save my money?

    I just wanted to let everyone know what I found out, just in case someone searches for this info later.

    The 2006 Haro X7 has the Truvative Howitzer BB in size 68mm x 50mm. I was able to contact Haro and get the info and continue riding until my parts get here. Thanks dog, you the man. I ended up going with the CrMo Team BB. And while I was at it I bought 2 of them. $29.99 each at pricepoint.

    Haha, while I was on pricepoint I decided to get the BB tool, some more grease, more chain lube, a chain cleaner, and a chain guide. That place gets me every time. Their prices are just too good to pass up.

    Can never have to many tools or lubes.

    Sorry about the vague post last nigh was getting late and had to be a early riser this morning. Too much like work to pay the bills then count the pennies for the bike bits.

    Before you blame it on the bearings, sometime the creaking comes from the threads...some grease on the threads usually quiets it, or making sure it's tightened.

    I replaced the bearing regardless. The bike has been ridden a lot since I got it in 2007. I weigh 300lb so it definitely gets lots of use.
