I've fitted a bigger axle (from a Pajero) to my AE86, it's now sitting quite close to the exhaust, the exhaust runs under the axle, there is probably about 3/4 of an inch clearance. With the suspension compressing it'd be a bigger gap. The issue is, if the car is jacked up from the chassis rather than the axle the axle drops and will hit the exhaust. I'm wondering if this will be an MOT failure? I'm going to take it to an exhaust place to get something with more clearance made up but i'd like to MOT it 1st so I can drive it.

Doubt it would be an issue

Edit: Reading failure - sorry. I'm fairly sure it would fail.

I am saying that. Did you not read the part where I said i'd drive it once mot'd to an exhaust fabricator and get something made up?

The car is currently MOT'd for another week or so but it's stripped down ready for a respray. The only potential failure I can think of is this exhaust/axle issue, otherwise it should pass. I'm thinking of taking it for an MOT before it goes for a respray, if it'll fail on the exhaust, I can go and get one made up 1st, otherwise, once it's painted in a month or so i'll need to get it trailered to an exhaust place, then to the MOT as it'll have no road tax.

Just take it for the MOT and if it fails you're legally allowed to drive it to a place of repair (as long as it's pre-booked).

If the vehicle fails the test and the certificate has expired, you can only drive it to:

a pre-arranged appointment at a garage to have the repairs done
a pre-arranged MOT test appointment

If it hits when the suspension is a full extension, could it not cause damage for example when going over a hump back bridge at speed?

Yeah, it'll probably rip the exhaust off

I can't see anything that'll give an outright fail as the suspension has got room to move during normal operation. There's only going to be a problem when the suspension is at an unnatural position and it'll only get to this position on the test to facilitate the checking of the suspension and the wheel bearings.

You may want to warn the tester to exercise more caution when checking the back end as it could result in damage to the exhaust. If the exhaust gets broken, then it could possibly fail for being not adequately supported, having a major leak of exhaust gasses and possibly for excessive noise.

It could also be a reason for the tester abandoning the test as he may not be able to get the rear suspension to a position where it can be assessed without risk of damage to the vehicle.

Am I right in remembering that hole in exhaust is a fail where as not having the whole exhaust is not a fail

Thanks for the reply. The place i'll use has a pit which is ideal. I plan on asking the guy that MOT's it to jack it up from the rear axle, that's probably standard practice on a old car with a solid axle anyway.

Not one's own driveway or garage at home?? wink

Just 'cos it's on dot gov doesn't mean it's actually or legally correct, "a place of repair" can be one's own driveway or garage - or anywhere off road wink .

OH, dot gov website and your propoganda! nono

Er, you're already allowed to drive it back home from the MOT test (unless it's a seriously dangerous fail).
