Well, I took out the dash and I added the white face thingys, and everything seemed fine. When I put everything back together the speedo would only go up to 35mph. So I took it apart again to see if anything was sticking, and everything seemed fine, everything seemed to move without sticking. I hooked it up again, and now the speedo work up for 40mph, which is better, but still not right. Does anyone know what might be going on?? It's one of those things where I'm starting to think I should have left is as was.:banghead:

Any help on this matter?

and why is that speedo cable so short?? How annoying! That the only thing I can think of is that it isn't in far enough... It is clipped in place though.

Thanks!
 
Is the speedo needle bent and catching on the new white face stickers? If it worked ok before that's all I can think of. Their pretty fragile so you may have bent it a little when installing the stickers. You can bench test it with a reversing drill that way your not having to install it to test it. No idea why the speedo cables too short unless someone replaced it and put the wrong one on the car. Mines plenty long.
 
Can that spring be fixed, or do I need a new speedo?

Maybe the speedometer can't keep up with the car? :burnout: :)
 
Hard to say without seeing it. On mine, whatever holds the spring in place was gone, so I used a piece of safety wire (lock wire) to hold it down and it's worked fine ever since
 
Speedo's can be fixed but it typically aint cheep and it really needs to be done by a pro. speedo cables are all short behind the IP...very few come out more than an inch or so ( if that) the idea being you undo it from underneath before you remove the IP.....IN assy they are put into the car already assembled and it depends on how far in the guy shoves it in and pushes the bendover on it....you can move them a little...but they will never come out far enough to unscrew them topside ( unless you have teeny tiny hands)
 
ALso....if you can screw the treads on it is likely in there far enough to engage and register....if it is showing 40 then it is spinnin.....and unless your needle is bouncing up to 40 then back to zero chances are your connection is OK
 
just a joke. The post didn't mention a mopar either.
 
Well... I took out the speedo again, and when I played with the needle, I pushed it in and there was like a "click" like something feel into place. So I put everything back togther and the speedo now goes over 40, but I'm also actully driving at about 20.
URGH! I can't win!
