Observations on D35 and why it breaks so easily!

I've been thinking about this a lot and have made some observations on why so many people seem to have problems with their D35 breaking.

The ring gear in the D35 is 7.5" I believe, same as the GM 10 Bolt that comes in S10, Camaros, Older model s-blazers, etc. I have seen several 10 bolts die under a camaro at the strip, and they all seem to have a common theme......The car is a manual transmission and the tires hooked really good off the line.

I've seen 10 bolt rears in AUTOMATIC tranny camaros hold up to 400+ hp running slicks at the track, lifting the front tires and last forever, but get one hooked to a 6 speed with some power and sticky tires and they leave a trail of pinion teeth down the track!

SO......here's my thoughts. Everyone here, or at least most that do rough wheeling, run with a manual transmission. It would make sense to me that the D35 would hold up a lot better with an auto tranny.

The main reasons that the 10 bolt rear hold up with an auto in high HP Camaros is because there is a lot less shock to the rear because the power delivery is a lot smoother coming from an auto tranny. No jerk from letting a clutch out too quick or powershifting.

Would the same not hold true for the D35? $400+hp to the wheels on a 3600lb car running slicks that stick to everything has to be more stressful that 180hp turning 35" tires. Right???


I'd like to hear everyone's thoughts on this. I have a 5 speed YJ now that I plan to trade for an auto shifting TJ next spring. I've been looking, and finding a D44 rear on a TJ is difficult. I want to run 33's or 35's without fear of my rear going and leaving me stranded. I was thinking i'd be safe with the automatic tranny?!?!?!

I think the D35 sucks because its a worthless freaking piece of poop that is just barely enough to handle a stock jeep. 9 incher here we come!

Now that is a soundly supported opinion!

I have to agree with Greg, as it is well supported with experience and facts as well as being explained in a clear, concise methodical manner. I have encountered the same facts in my research to switch from slush box to stick and many hardcore wheelers have told me to stay with the auto just because it offers so much buffer between the power and the parts that break. I am STILL trying to decide what to do but the more I learn, the more inclined I am to stay w/ the auto despite the fact that it is a real power sucker on a 2.5L and it doesn't offer the same reliability as a manual(bumpstarts and running w/ low or no lube/fluid) Plus, it is a heck of a lot easier and cheaper to not have to rewire and swap out Tcase inputs

well i'm not saying that a 44 wouln't be better, but since that is or simply unavailable or unpayable, i'm making the best of my 35's i do some seriuos jeeping (altough not rock trails.... are non around here) and untill now it helt fine (even where other 4x4 had to lip of the trail)
i dont think the abuse on an axle is axualy comming from popping a cluch to fast :-)

Who has had a D35 go bad on them?

What's the full story?

I have been reading the stories about how bad they are but never heard a personal story with one going bad. You can up grade them but I agree it is cheaper to get a bigger axle D44, F9”, F8.8 or ect. but if you stay under a 33" tire and not use it as a drag racer you should be fine.

I grenaded mine a couple of years ago. I was in two-wheel drive following a couple of friends in their full size Chevy’s. We were going through a loose section or trail and started to get on it. Well here I was about 20mph and fishtailing when I hit a section of hard pack. Clunk, Snap, Bang and Boom. I was able to limp home at about 10mph but when I made a turn in either direction I felt like the entire rear-end was going too far out. It was still under warranty so I towed down to the dealers and had them open and inspect. $1600 dollars of parts and labor latter I was back on the trail with all new internals. Warrantees are sweat, only cost me $200 for my deductible. I babied my D35 for A while and after the warranty ran out I install a Ford 8.8 .
