Installed 4.30s now have vibration and buzzing at about 75mph....kept the stock driveshaft. Would an aluminum driveshaft take care of it?
I know it sounds insane but I had a similar issue and was going to tear the rear end apart but had to get a clutch done first because of a bad throw out bearing... believe it or not now that clutch is done I don't have what I thought to be a rear end problem... mine would "whine" on and off the gas only in 5th but went quiet when clutch peddle depressed now with new clutch the whine is gone
Did you make sure the backlash is correct? I'm pretty sure what you're experiencing is coming from the diff. so an aluminum driveshaft would just make the buzzing louder as it transfers sound better than steel. If a shop did it, take it back as soon as possible and make them redo it. If you did it, you need to go through it again and make sure everything is within spec. I had the same issue after putting in 4.10's. The backlash drifted off from spec.
Yeah I could feel a light "thumping" feeling in the shifter... it also had a "knocking" sound when idleing in neutral if you put yourhead near the shifter like it was banging around
My throw out bearing was trashed when removed all is well now... if you can afford it I highly recommend a light weight flywheel I did a fidanza flywheel andclutch kit the flywheel made a huge difference in acceleration in my opinion it revs super fast now
Thats not a bad price at all for all that....i drive a 4runner as my daily as well, cant go wrong with a Yota daily. Just sold my 72 Fastback...what year lightning? I want to get my hands on one of those if not a Termi.I bought the fidanza kit... it comes with the aluminum rebuildable lightweight flywheel,pilot bearing,puck style clutch disc, pressure plate and throw out bearing all for $600... I just had mine installed 50 miles ago so I'm not sure about longevity just yet but like you it's not my daily driver either... I've got a lightning,ole lady's Toyota, and company truck as well
