TTR uprated diff top mounts

Hi,

I'm fiiting these to my Sprint, this weekend. TTR are closed until Monday, so cannot ask them this question. It may/may not be relevent:

The fixing bolt is part shank, part thread.

The ones I removed, were inserted from below, such that the unthreaded shank sat within the lug on the diff, whilst the threaded section sat within the metal sleeve of the bush... the nut being in the boot.

I'm no engineer, but it "feels" right that the bolt should be fixed upsidedown.

Does it matter?

Regards,

Stuart.

I personally dont think it really matters which way up the bolt goes (though I always fit mine with the head on top and nut on the bottom). The only thing to avoid in general with a bolted joint like this is to not have the threaded portion of the bolt in the section where the 2 components join.

Movement at the interface between the 2 components can overload the bolt at this point and the bolt is less likely to fail if the theads are total inside one of the two components being joined.

Makes sense.
