Default 95 speedometer

Bad speedometer gauge for a couple years now, and am finally getting around to tracking down the issue. I seem to remember it going bad a little at a time and then finally just giving up altogether. Will actually start out on zero when i start the truck and then slowly creep up to 100 as I drive with no relation to anything except for how long the truck is on.


I have tried a few things I picked up on other IN threads so far... Replaced the speed sensor because the computer was flashing the vss code - no change. pulled the gauge cluster and cleaned and tightened everything (even removed the speedometer gauge from the cluster and sprayed it down with electrical contact cleaner) - no change. Also tested/swapped some relays around to see if there was a cruise control issue causing the problem - no change, but found a crumbling diconnected cruise control vacuum line in the process and replaced that...


I have looked everywhere and all I can find are complete clusters for sale on Ebay. The pathfinder clusters with the additional clock go for like $300 if they are in really good shape. No way I am going to spend that much, ha. My question is can I replace Just the speedo gauge with one from a non-matching truck? for example I have a V6 4x4 5-speed, so I know the cluster is different for say a 4cyl 2wd auto, but is the speedo gauge itself the same on those two vehicles?



If so, I have no problem popping back open the cluster and removing the 4 screws and would much prefer to buy one of the cheaper 4cyl clusters...

I’m pretty sure you can just swap the speedometer assembly. I bought one from David29 for my son’s truck. I’m sure he can tell you exactly what you need and there’s a good chance he will have what you need for sale.

Default Speedo Swapped

I did this over the weekend. Took about 30 min total, but I have had the cluster out before so was easy. Bought a low miles cluster on eBay that had a scratched glass. Popped out all the gauges and swapped them into my assembly. Speedo works, CEL is off, and I have about 200k fewer miles now, haha.



Only thing is I think the new cluster came out of a 4cyl because the tach seems a little off. In 5th gear it hits the red line at 6k rpms right at 80mph. It is not too bad and I shift by engine sound anyway. I might switch the tach back, but I am not sure if the old one is good or not. Anyone know what rpm I should be at in 5th at 80mph? Seem to remember a couple years back (the last time I was sure the tach was working) that cruising in 5th on the freeway it would be at 3.5-4k...

Idle is at 1500rpm, is this too high? I still have the original tach. I saw elsewhere on here where someone was attempting to recalibrate one from 4cyl to v6 by the blue adjuster knob on the back. If i set the blue adjuster on the new tach to the same position as the original would it then read correctly?

Yes. That is supposed to be how to set the tachometer.

Change that blue knob on back of tach to roughly the one o’clock position and you will be golden.
