Outer Limits 4x4 Board

ok looking into this for a friend, who's looking to swap a hilux front axle into his ferroza and needs the 5.29 diffs to match his rear.

people are saying these are weak etc... well who's run them, who has or hasn't broken them, and what combo wheels motor chassis/body were you running. just seeing.

oh and am i right in assuming that lux lockers will fit these centers

m8 of mine ( see evolution zook build up in the members section) he runs a 1979 hiace centre that he rebuilt with new bearings etc. he has this diff under a zook running 38.5 super swampers. hasnt had probs yet.

he hasn't had it on the road all that long though has he?

Are the aftermarket 5.29 gears, such as from don kyatt, better/stronger or are they just factory replicas?

Are there stronger aftermarket alternatives to factory/replacement factory gear-sets?

In my opinion based on personal experience, the 5.29's found in HiAce are unlikely to be quite as as robust as the aftermarket Lux replacments (the crownwheel in HiAce 5.29's is considerably thinner, plus age).

If you are looking for STRONG 5.29's you can't buy better than YUKON GEAR, ex US. You pay a little more but ya get whats ya spends.

There is much conjecture as to how much weaker 5.29's are from 4.88's and below in real world application; in my experience and estimation - some but not necessarily significantly so. This opinion follows from Surf with 5MGE, 5.29's, Marlin Crawler 2x2.28, front/rear difflocks, 35" Simex ET's. Have busted more CV's than I've had hot dinners, but never had a 5.29 shit itself yet (including the HiAce stock). The real secret to maximise diff stength is make sure they are set up precisely, with good supporting bearings, correct meshing and backlash.

Have made the transition to Yukon Gear kit with pending 1KZTE transplant, Longfield 30 spline super axle set, chromoly rear axles, and 37-38" Creepies. Time will tell.

no he hasnt but he doesnt hold back when off road!!
The rebuild kits were only $100 each, a good investment i think.

Mind if I ask what the damage for the Yukon gear set was?

In AUD $197. plus shipping - thank you E-Bay.

Shipping is oftentimes where it hurts; if one's not in a hurry USPS Economy Parcel Post Insured in the way to go. Never once have I had any problem with the US Postal Service, unlike the more expensive courier carriers.
