rear suspension arms binding?
hi there,
i keep having this trouble with my back suspension arms binding on my losi 8ight 1.5 and not moving freely an dropping down when the shocks aren't attached.
i know it is caused by the hinge pin and suspension arm but it is ok once i clean it out but when i come to cleaning my car from a meeting they bind?
is there anything i can do to prevent this?
many thanks
lewis

Hi.
I've had the same problem on my buggy. In my case the metal suspension pins rusted a little. I removed the rust and put on a little bit of oil on the before refitting and I've no binding anymore.

Generally after every race weekend, I'll pull all of my suspension arms off, run a reamer through the holes in the arms, and buff my hinge pins with a Scotch-Brite pad. I've found that it's just a small coating of grime that causes my arms to bind a little. Doing this as part of my post-race cleaning routine keeps them moving smoothly.
I've also used a little dry graphite lube with good results. Check your local locksmith shop if you have trouble finding it elsewhere.

another case could be the outer hinge pins are bent, or the hinge pin holder could be bent.I have never had a problem with arms that was not one of these problems.

hi,
thanks for the replies.
i will have a look into bent hingepins but it has been happening for a few weeks. i give my car a good going over before each meeting. so i clean my car and check suspension movement, anything bent or broken.
and when i go to clean my car after a meeting the rear suspension arms are binding where as before the meeting they where moving fine.
could it be a mixture of dirt and oil from the exhaust because it only seems to be the suspension arm behind the engine and exhaust, i think it is the left rear suspension arm?
if the hingepins aren't bent then i will try that oring idea because i have some old losi shock orings.
many thanks

O ring's or the little foams donuts don't do anything if you ask me, been there done that and it Didn't help. I feel some tracks dirt makeup is just more prone to making thing's bind up and squeak over a day/weekend of racing.

I'd rebuild the shocks and in the process completely clean ever thing and check if any of the shafts are bent even slightly. sometimes you can't tell just by looking at them I normally roll them on a table and you will know right away if they are bent. after that refill the shocks and check if they bind at all before installing them.

Another thing to look at, when you secure arm holders/diff case together, just screw tight enough to close the diff case. You want to have a tiny, tiny bit of front to back play between the arm and the holders. If you screw them together too tightly, they will cause the arms to bind.

i will try that but there is a washer between the suspension arm and the rear hinge pin brace, should i remove the washer and see if that helps?
