Zlich Posted November 8, 2012 Author Report Share Posted November 8, 2012 I have done that a few times it does it no problem. Quote Link to comment
ggzilla Posted November 8, 2012 Report Share Posted November 8, 2012 Great! Glad to hear it can do 60 mph now. Quote Link to comment
Zlich Posted November 8, 2012 Author Report Share Posted November 8, 2012 not recently but it can go to 5000rpms when its just sitting. if thats what you mean. Quote Link to comment
Zlich Posted November 8, 2012 Author Report Share Posted November 8, 2012 like when its in neutral Quote Link to comment
ggzilla Posted November 8, 2012 Report Share Posted November 8, 2012 You lost me. I understood you to say your were in fifth gear at 5000 RPM. Now it won't rev that high except in nuetral? 5th gear and Im normally around 5k rpms and doing around 50 55 maybe Quote Link to comment
Zlich Posted November 8, 2012 Author Report Share Posted November 8, 2012 oh no. sorry I got confused on if you meant when Its in gear or not. yes I believe in 5th gear it goes around 5000 RPM. I know it hits 50-55 because thats the speed limit for me to go from my house to school. Quote Link to comment
Zlich Posted November 16, 2012 Author Report Share Posted November 16, 2012 okay sealik I calculated the gears I dont think its right but I spun the 29" tires 10 times and the driveshaft spun 20 times and almost made it to a even 21. Im thinking its like 20.75 rotations on the drive shaft but I did the math and got 4:15 gearing and that doesnt sound right. Quote Link to comment
datsunaholic Posted November 16, 2012 Report Share Posted November 16, 2012 Are you sure you don't have the transfer case in LOW range? Because that's the only way I can see you hitting 5K in 5th and not be doing close to 100MPH. 1 Quote Link to comment
Zlich Posted November 16, 2012 Author Report Share Posted November 16, 2012 what do you mean in low range? and I cant exactly remeber what the rps where for sure but I know they were high. and I cant take it out right now because Its not running. Quote Link to comment
datsunaholic Posted November 16, 2012 Report Share Posted November 16, 2012 It's a 4X4, right? It has a transfer case shifter, right? They have 2H, 4H, N, 4L positions, unless it's some wonky full-time 4WD that isn't stock. You should be turning somewhere close to 3000 RPMs at 60MPH if it's stock. So either it's not stock, or something isn't right. Likely cause: 1) The tach is lying. 2) The transfer case is in low range Slightly less likely causes: 3) Your clutch is slipping beyond belief (but you won't be able to go up hills if it was slipping that badly) Possible but improbable: 4) It has 5.11 rock crawler gears in it, in which case you should not drive it on freeways 5) Your speedometer is bad and you're really doing 90MPH.

Zlich Posted November 16, 2012 Author Report Share Posted November 16, 2012 its in N and It was driven from bend oregon to washington If my speedometer was off Im pretty sure I would have been pulled over. But I also checked and the speedometer is accurate. I have only driven it 1 time on where it needed to go 60+ the rest of the time the highest was 55. I cant remember my rpms off the top of my head.

ggzilla Posted November 16, 2012 Report Share Posted November 16, 2012 With 5.1 gears you can still do 60 mph with the smallest 14" tires. You are measuring something incorrectly Quote Link to comment
Zlich Posted November 16, 2012 Author Report Share Posted November 16, 2012 ggzilla any idea on my gear ratio? I might go and check it again a little later and see if I get the same numbers cause im not to sure on if I have 4.15 or anything of that sort for gearing. Quote Link to comment
Sealik Posted November 16, 2012 Report Share Posted November 16, 2012 okay sealik I calculated the gears I dont think its right but I spun the 29" tires 10 times and the driveshaft spun 20 times and almost made it to a even 21. Im thinking its like 20.75 rotations on the drive shaft but I did the math and got 4:15 gearing and that doesnt sound right. You have 4.11s........ Better confirm that the front diff is also the same ratio. Looks like the gears/diffs were swapped at one time....being that your ID plate states 3.89s Quote Link to comment
ggzilla Posted November 16, 2012 Report Share Posted November 16, 2012 Yes, 4.11. If it was lsd, both wheels will turn 41 times when driveshaft is turned 10 times. For open differential one wheel stops while the other turns. Or if the wheels spin differently, your estimate is all wrong. Quote Link to comment
80daterpillar Posted November 17, 2012 Report Share Posted November 17, 2012 Seems to me to be quite obviously in low range... Shift the transfer case lever. Whats your max speed in 1st gear, like 3 mph??? Or the tach toast. Listen to datzenmike, he's always right... If he's not right, it's cause he said he wasn't. Damn... Quote Link to comment

For open differential one wheel stops while the other turns. Or if the wheels spin differently, your estimate is all wrong. well I jacked it up from the center so both wheels were in the air and I got no were so i just jacked up the passenger side rear tire and spun it forward and got the 20 3/4 of a spin. Im sure it was less than 1/4 away from being at 21 rotations. I wouldnt mind having a lsd thought. well atleast now I know I have 4.11 gears. how would I calculate my front end? I only have one cv axle right now Quote Link to comment

There's no way you could drive from Bend to Hoodsport in N. You couldn't drive 6 inches in N, unless it was all on a hill. If it's in N you shouldn't be able to drive anywhere. That's Neutral. It disconnects both front and rear driveshafts into freespin. Since N is NOT next to 2H, I now give higher creedence that you actually have it in 4L. 720 T-cases are (from front to back) 2H, 4H, N, 4L. Quote Link to comment

I couldnt tell you right now it doesnt run but in 2wd its like 10 15mphs I havnt taken it out in 4wd because theirs no point I only have 1 cv axle. Quote Link to comment
Zlich Posted November 17, 2012 Author Report Share Posted November 17, 2012 datsunholic let me run out and check I cant rememeber what its in all i know is I havnt touched that lever at all since I got the truck. Quote Link to comment
Sealik Posted November 17, 2012 Report Share Posted November 17, 2012 Lever would be pulled all the way up/back for 4L Quote Link to comment
Zlich Posted November 17, 2012 Author Report Share Posted November 17, 2012 yeah Its all the way down and the lights not on for the four wheel drive. thats the only reason why I know its not in 4 low Quote Link to comment

There IS absolutely a reason to take it out of 4wd... wear and tear. No reason to have the tcase/driveline/etc spinning if it doesn't need to be. And have you ever lost a front driveline on the freeway? I have... not fun. No point in arguing about this until you have it running, but there is NO way you are doing 5k at 55, without something being wrong. period. Quote Link to comment

I meant I havnt engaged the 4wd at all since I have gotten it. Its been run in 2wd since I got it running in august. I have no reason to put it IN 4wd. I dont have the driverside cv axle.
