i was told the main reason the abs lights come on our because of a bad speed sensor? would that also affect my speedo being off 5 mph? and if i do replace it will it fix the speedo problem or will i have to get a different gear for the cable?

 

On your 97, the speed sensor is in the back of the Transfer case, the abs sensor is on top of the rear axle.

Speedometer error is usually caused by having non-stock sized tires on the truck. Check your door sticker, see what IT says should be on the truck, then check your tires, and see what size actually ARE on the truck. Do they match?

 

the speed sensor is in the t-case, but i beleive the lights indicate a bad RWAL sesnor in the rear diff.

you dont have a speedo cable. only varibale w/ speedometer reading is tire size and gear ratio. do you know the specs on either? compare them to stock specs. you can buy a different VSS gear to compensate for change in either.

 

tires are 265 75 16, and my gear ratio is 3:55

 

Probably came stock with 245s? That would account for your speedo error.

 

it actually calls for 225's. is there anyone of fixing it? other than putting stock size on it

 

Check and see if you have a VSS in the output housing of the t-case. If you do, you can get a different gear for it, to correct the error. If you don't.... reprogramming is the only way.

 

ok not sure but the other night on my truck i was taking some backroads back from my favorite adult establishment. and it had been snowing i went to turn and got on the breaks VERY hard to slow the truck before the ditch well... i managed to slow down enough but i still went to the ditch lol... well this story was to tell you that my abs and emergency brake light were on...i just got my truck out and drove home and the next morning i checked my fuse. it was blown put new fuse in both lights went off

 

'97 will have a VSS, something like a 30 tooth gear should correct the speedo

 

+1 on the fuse, that's most likely your problem Ram King. I had those same lights come on after i hooked up to a trailer that had been wired wrong and it blew me fuse for those lights. Its the same fuse for both. Check it, and replace if bad.
