CV Axel Rubber keeps cracking

[BlackWorksInc]

They've always been that tri-lobe shape on the 4th gen, 5th gen, Tacoma, and FJ. This is part of why we stopped offering reboots on anything except factory axles; even the aftermarket ones that look like factory axles seem to not fit properly with factory boot kits.

I don't know what are you talking about.My T4R is 2004 model,CV axle is genuine and my cv boots are original Toyota's. They are not tri-lobe shape. They are both rounded inside.According to VIN, this CV axle has been installed in 2002-2004 production.

Me either, my '04 has the same triangular looking inboard tulip housings as I mentioned. Nor have I seen another '03 or '04 with anything but those? All the V6 & V8 4th gens I have seen have had that style of axle and we've never stocked anything other than one style of factory boot for them.

The part number for US bound (GRN21 & UZN21) 4th gens for the CV axle boot kit appears to just pull up as: 04438-60030, if I have time tomorrow I can bug my parts department and see if they can find a different axle part number or boot kit beyond that?

I'm not too familiar with anything beyond what was sold/sent to the US, so I suppose it could be possible that they used a different axle for early production 4Runners & Hilux/Surfs?
