Slip/Abs/brake light all come on after tire change and 4.08 install problems

Chasingstatus

Hey guys I hope this hasn't been covered already I couldn't find any info in my searches due to the nature of the question. Basically after about 9.6 miles on the odometer my slip, brake, vdc, abs lights will light up. I installed 4.08 gears over the winter and everything is hooked back up correctly, wheels speed sensors and all. here's where I think my issue is though since I don't see others with the issue with gears. I am running a 255/35/19 front and 305/35/19 I remember there was a calculator or something that told you if your sidewall heights were within a certain number from each other to keep the speed sensors happy since the rears are a lot taller than the fronts. I cannot remember where this link was or how I found it but I am hoping for that since the gears make no noises and perform well. thanks in advance

Also brake fluid level is good

I'll give it a shot. Could be your tire sizes. Using the TireRack Mich PSS sizing specs. Your fronts are 26.0" dia. Your rear is 27.4" dia. That's almost a inch and a half difference. If you went with a 305/30-19 on the rear. It's 26.3". Or a 255/40-19 on the front. It's 27.1".

Ok cool thanks that's kinda what I was hoping to hear I couldn't remember where the link was to a good tire calculator. There was a good one on my350 years ago that told you the percent you were allowed to get away w

You won't damage anything. When you dyno. The rear tires are spinning, and the fronts are stopped. Some of those idiot lights come on anyway.

I don't believe it's your tires or wheels. I have had my 4.08 for 5 years with 20 wheels and zero problems

Hmm possibly your rear sidewall is too tall? I ran a rear tire size of 275/45 and those lights came on, but also my speedometer didn't work; therefore, my odometer didn't work keeping miles from being logged.

Yeah it's def not the gears. I had a Nissan tech do all the work and I installed the diff. I think Rusty has it correct tho.
