Is the 150 showing any signs of cracked inner guards

[Dusty74]

Surely now that Toyota have changed the design they concede fault on their part and will honour warranty for any failure?

Haven't checked whether the diesel has a different guard, there don't seem to be any petrol models with cracked guards on this forum.

The diesels have the same part numbers too

The guard in question looks to be 53701 and 53702 in toyodiy, called apron sub-assembly

Interesting to note the 2 different part numbers for different years.

Looks like it changed in 2011, maybe Oz is just the last place to get the change?

They are part numbers for the petrol. Haven't checked whether the diesel has a different guard, there don't seem to be any petrol models with cracked guards on this forum.

Hi Krypro,

I have not seen a new style inner guard yet but from what i can see the 2nd skin looks like an addition to the original guard, does that sound right? I wonder if toyota would sell just the second skin part and spot weld these onto the original 150 inner guard?

The top of the guard is identical between the two designs, the only difference is the shape of the stress bearing lip which has had all holes removed, has a rounded bottom and has a short backing strip in the high stress area.

Interesting, a friend has recently purchased a 2014 model, it appears to be the updated model with the new features.

However when I checked the inner guards it appears to have the same as my 2012 and not the newer style mentioned in Krypto's post.

Will have to check more closely what model he has when I see him next.

When we had a look in the yard we saw two 2014 models with the old style guard and the rest had the new guard. We thought it was probably Toyota using up old stock of the guards before moving to the new design.

Given the low number of guards that crack it was probably cheaper to use up all the old design guards.

Finally had time to have a look at the new guard design, picture attached below. Also included a picture of an old style cracked guard.

I don't think bolting would be a good idea as it would increase the stress concentration factor if the holes are drilled into the guard near the bottom lip. I would consider building a new "bridge" to have the battery mounted to it and the "bridge" would span the entire wheel arch.

Nice idea and I've looked at it but very difficult to implement.

Would a thin strip of zinc anneal sheeting about 1.6mm thick (or less if need be - .8mm) & 20>30mm wide moulded to the contours of the guard and & then bolted in place do the trick ??

I think it should help and I'm thinking of doing the same. I was looking at using aluminum strip.

The tricky part is attaching to the guard, to ensure load transfer it needs to be a good joint which if using bolts means good surface prep and proper tension to ensure proper friction for load transfer. Also unsure about where to drill holes if I do it.

Thanks for the info krypto, very interested to hear how your mate goes with getting the new inner guards fitted.

See no reason why not, every thing else is identical. But.....huge job and pretty sure dash would have to come out.

Wouldn't be that hard for Toyota, or someone with the right equipment to fabricate an add on fix.

If I still had access to a fabrication shop id have a go.

Thanks for that Steve....

Very interesting to see the difference between the OLD and the NEW designs...... Wondering if the NEW will fit onto the OLD model 150's ??
