    03 VT 2 - slop in rear pivot

    Hey foks,
    I have only had this particular VT for about 3 weeks and have done maybe 9 rides in that time.

    Anyway, I noticed before I rode today that there was some play in the around the shock/pivot area. Two of the pivot bolt/bearings where loose, so I tightened them and set off. I have been cleaning it after pretty much each ride, and I had not noticed anything loose or any slop before today.

    Anyway, there never used to have any play, and it is still there despite tightening the pivot bolts.

    Any thoughts as to what it might be?

    I've have quite a lot of slop in the bottom shock bushing that can be both felt (and heared) when riding and when rocking rear wheel up and down. My LBS says its normal, but i dont think so. I can even rattle mounting hardware inside shock eye bushing, way too much play to be a working play IMO, but i'm no expert and i can be wrong.

    Something similar happended to me, just before starting a ride I noticed a loose bolt on one of the suspension linkages. I tightened the bolt and proceeded to ride with no problems.

    What I did was to consult the owners manual for torque specifications and type of thread lock to use on those bolts. I re-applied blue thread lock (loctite) and tightened the bolts following Giant's torque measurements, since then no more loose bolts.

    Recommendations:

    1) get a torque wrench in inch/pounds (not foot/pounds)
    2) get blue loctite
    3) read your manuals
    4) remove all bolts
    5) re-apply locking compound
    6) tighten following manufacturer specs

    For the play issue, could be a defective bearing or bushing. Take it to the LBS and have it checked.

    Good luck!

    After yesterdays ride I looked at my bike and saw that one of the upper pivot arms was missing the bolt. I took it off and could see that the bearing had completely disintegrated. I pulled the other pivot arm off and saw that the other washer was in the middle of disintegrating. These bearings looks kind of like pilot bearings which last a long time in cars. These two didnt even last a year. I took the pivot arms to the LBS and last I saw the mechanic was having one hell of a time trying to remove what was left of the bearings. Giant put in light bearings to save weight.. The LBS mechanic said they were too light. An automotive pilot bearing is heavier. This is my first full suspension bike, so I just learned something on dirt and pivot bearings. Interesting the two bearing that attach to the rear were ok.

    hmmm

    despite the advice with tools etc (I only have my Alien with me - the rest is at home in Australia) , methinks I will take it to the local Giant dealer and ask them to have a look and see.

    Definitely do not want to hear them say "oh that is normal"..

    Does anyone know where I can find something on the Giant warranty policies?

    hmm, i've also heard of this problem before though i've never experianced it myself, i think this was actually from one of the very few bad reviews of the VT's on mtbr...

    slop not normal

    On my 2003 VT1, I've had slop develop on the upper shock bushing. They put new bushings in once, but it's started to get sloppy again. This seems to be a defect. The other pivots I've had no problems with - they're all bearings I think.

    Well after calling every Giant Dealer around. No one has the parts to fix my bike. Of course its not under warranty and I will have to order a full bearing-screw kit to get the bike back on the road. My guess is the lateral movement led to the eventual disintegration of the upper pivot arm bearing. The LBS guy asked me if I hosed the bike down after rides, he thought that led to the failure. These bearings are 19x10x7-rubber sealed, very hard to find. I am changing my opinion of the Giant VT-its a good bike-when its working. Dealers did have NRS parts-so failure isnt totally uncommon. These bearings should not have failed in one year.

    Bearing specialist?

    Is it possible to go to a specialist bearing retailer and buy the bearings thru him?
    Cheers

    I did actually talk to the Giant rep in Vancouver. He told me that they do not use special bearings and that it would be possible to get bearings from a bearing shop. He mentioned some names buit I can't remember who.

    He also suggested that I check the pivots etc. So I re-checked them, and realised that I had never checked the bolt at the bottom - the one which allows you to adjust the suspension from 5.7 inches of travel to 5.0 inches of travel.

    Anyway, that had worked a bit loose as well. Once I tightened it, then the play went away.

    Moral - check the pivots carefully before every ride!

    and I am going to get some loctite.

    That bolt that adjusts the rear travel from from 5 to 5.7" certainly needs some loctite on it. You`ll see the original loctite color still on the bolt when you remove it.
    I had read somewhere (cant remember where though ) that the bearings used in the VT`s pivots etc were readily available at most bearing supplies shops. Sometimes its easier to bypass the LBS and get these sort of things from other suppliers
    Cheers

    I checked with one bearing shop, seemed like they should have something. They didnt. The bearings for this bike are od-19mmxid-10mmxh-7mm. I could see where the bolts had been installed with loctite.. I posted on another forum and another VT-owner reported the same double bearing failure and said he got rid of his bike partly for that reason. Its been 11 days since I called my local dealer. He said the bearings are being sent out through the Giant Warranty department-causing a delay. I know I am not covered by warranty but maybe Giant will replace the parts if they have been having a problem. A bolt coming loose might have led to the failure on one side, but on the other side the bolt was tight, it was only when I loosened it that I could see the bearing had failed. I will put a follow up on this to let anyone interested in what the cost was if any.

    I am very interested to find out how you go with this, and I would guess that all the other Giant VT owners would be also.

    Please let us know what happens and whether or not you are able to get some satisfaction from Giant with the bearings, etc..


    Thanks,


    R.

    Loose bolt

    A loose bolt on either side could possibly end up damaging both bearings given that this will cause additional play/movement on the bearings.
    I wonder how many others have had bearings fail in a relatively short space of time?

    I finally got the parts from the bike shop. Giant does not ship bearings, if the bearings go bad you get a whole new pivot arm. The bike was not on warranty, but the cost of the pivot arm was only $5.00 each. Unfortunately they did not ship the bolts, spacer and washers. After looking at everything I realized that at least one of the washers that went around the spacers outside the bearing was missing and had either not been installed or had failed along with the bearing and had fallen off. The spacer and washer were missing from the side with the missing bolt. I bought a bolt at the hardware store for a temporary fix.
    I am now thinking that the failure of the bearings might have been from someone not installing the washers around the spacers or the washers failing and coming off the bike leading to slop in the pivot. The washers are plastic or fabric. As far as tightening these bolts I can see that they probably are installed at no more than 10 foot pounds of torque, maybe less. If you tighten too much you simply are increasing the dampening action on the shock. That where the loctite comes in, tighten just enough to get the slop out. When the bolt comes in I will ask the shop guys what the correct torque is on the bolts.

    Idea! A place to find replacement bearings

    Hey,
    I hope I'm not too late. I, like the rest of you have had the same problem, except one of the bearings dust seals came out and ruined it. As mentioned in an earlier post, the dimensions are 19mmx10mmx7mm. I looked online and found a place that sells 10 of them for $19.95. They look a little more robust. Check them out at http://www.vxb.com/Merchant2/merchan...gory_Code=10mm
    I personally havn't tried them yet but I just ordered them. I'll let you know if it fits.

    Also, If you feel some slop in the rear end (knocking noise when you lift up the seat), then you will need to go to your LBS and get a replacement bushing kit for your Swinger shock. Hope this helps.

    I have to get new bearings for the 03 VT 2, and I was wondering whetherthese bearings fitted well.

    Yeah, the bearings fit great. I got the nickel plated ones in a pack of 10. If you need some help installing them, email me at plgabor@yahoo.com. If you don't have a vice, I would recommend just going through your LBS. Its virtually impossible without one. Hope that helps
