Author Topic: 5.29 gears (Read 5402 times)

I have heard that 5.29's are easy to break but if running 35's or larger tires you will need them so how many out there are running 5.29's and issues with them.

I also heard of sometype of cryo ring gears or something like that which make them stronger. Has anyone tried these and if so was it worth the extra cash.

5:29s on 36 parnelli Jones. No issuse for last year with the gears. 4cyl great on power . I've hit 80 mph on the freeway at 2500 rpm in 5th gear.

529's are strong , its the toy 571's that people talk about breaking

BS - 5.29 and 5.71 both have 7 tooth pinion - same strength. If you're concerned about the strength, better go 4.88 or higher.

The 571's WILL BREAK, I snapped the pinion of in the front, it sucked the head of the pinion in the diff and locked up the front end up, had to pull of the hubs and get winched out...........what a nightmare. Ohh btw....Im runnin 488s w/ 37s now....

With the 4.88 is that enough to pull the 37's easy?

I have 4:10s still and it is time for gears so I am wondering the same thing? 5:29 or 4:88 I am running 37 toyos and will probably go no bigger. I use it as a dd and would like deacent speed at low rpms, I have to use 2nd to get to the high lakes or any othe steep incline it sucks.

When you install new gears you have to break them in properly or they will break. Also it's driving style

fullthrottle · « **Reply #10 on:** Jun 18, 2007, 01:47:51 AM »

the bigger the gear ratio the weaker the gears are plane and simple. cryoed gears are stronger but the previous statement still stands.
i my opinion proper gear setup is the most important thing. the people with properly setup gears that brake them like the skinny petal to much, and s!@# hapens. for the most part people that brake gears only brake the teeth this can happen many ways but it is least likely for properly setup gears to brake this way no mater what the ratio because 4.10's and all aftermarket gears have the same gear geometry and there for the teeth are vrchualy the same seize be for you yell they can't be look at this (http://www.gearinstalls.com/410suck.htm).
now be for some one comes out any yells that they shered the pinion head off, ask were did it brake. right at the inner side of the inner baring race; right, well no mater what gears you have the OD diameter ware the baring preses on is the same.
get some 5.29's with your 35's, it's the closest Mach to stock ratio

mudmaster · « **Reply #11 on:** Jun 18, 2007, 05:40:21 AM »

5.29's and 36's. No issues

Tallchevy · « **Reply #12 on:** Jun 18, 2007, 08:32:31 AM »

My cuz had a 1st gen with stock gears & 40's. It was a show truck daily driver & only drove it on the street (I know, what a waste). He broke the stock 4.10's.

5.29's are not strong in anyways. unless you have them cryo'd. buy some and send to bobbylong, or performance cryo.

Loosekannon · « **Reply #15 on:** Jun 19, 2007, 12:18:56 PM »

I have Yukon 5.29's I have been wheeling on for over 3 years with 38's and havent had a prob. Go out to the Hammers alot too, well thats about the most of my wheeling.

they have some highway miles on them too. Drove to Vegas a couple times with 35's on. They just keep going...and going...etc...

808-Yota · « **Reply #16 on:** Jun 19, 2007, 03:07:13 PM »

I'll try the 5.29's just got to keep an extra set up in the tool box when wheeling. It will be mostly mud and sand since there's not much rock crawling here so I think that they should hold up.

Different sizes

Same # of teeth but different size due to the different size ring gear

808-Yota · « **Reply #18 on:** Jun 20, 2007, 02:56:36 AM »

So the pinion is the same but the ring is smaller.

kneedownnate · « **Reply #19 on:** Jun 20, 2007, 02:56:44 PM »

Same amount of teeth but differnt size ring and pinions. Lots of people just assume they're the same size due to having the same # of teeth, but they're not considering the ring gear either.

lilbuddy · « **Reply #20 on:** Jun 20, 2007, 03:11:11 PM »

Ive broke a set of 5.29s with my 37s after 2 years of wheelin and 3 years of DDing.

Toyota axles suck, just keep the money you have for the set of 5.29s and put that into a set of 5.38s for some 60s or something.

Yes, but not significantly (you can only vary the size a small amount and still have the proper gear for mesh), and when you consider "teeth in mesh" the number of teeth has more to do with it than size. There is a considerable step up in the attention to detail required to properly set up (having 3 teeth in mesh at all times) 5.29's or 5.71's over 4.88's, which are a step up in difficulty from 4.56 and 4.30.

If you're claiming the ring gear is the weak link, see the side by side photos in the link above. Lower gears have MUCH stronger ring gears than higher gears.

Long story made short, the lower the gears the more critical the setup, and this is ESPECIALLY true of 5.29 and 5.71 Toyota gears.

most of the people with 571s breaking are due to improper setup

A little off topic put what brand is better? I have seen a sale on motive gears are they any good?

I've got Motives in mine, they seem OK. Zuk doesn't mind them.

Lots of people run 5.29's no problems. Post up a poll and you will see. I run 4.88's and wish i went 5.29's. Toy axles are plenty strong for the wheeling you said your into.

Tallchevy · « **Reply #26 on:** Jun 21, 2007, 08:04:23 PM »

A friend of mine just broke his 4.88's with 33x10.50x15

Those were Genuine Gear brand.

people break genuine gears on a daily basis. thats nothing new

yukon is the best.
i run 37 toyos on my 86 runner and i run 5:29s.i wouldnt go any higher.
i just broke the carrier and the gears woulda been fine but i had to drive it 5 miles back to camp

~tc~ · « **Reply #29 on:** Jun 24, 2007, 06:18:13 PM »

Just to be clear, Yukon does not make gears. They are simply sets of Richmond, Precision, or US Gear gears (there may be others in there too) in a Yukon box. I would not put the Richmond gears in the same class as Precision and USGear, so there is no way I would say Yukon is the best.

As for what to buy, spend the money on a great setup - that will make more difference than what brand the gears are.
