Banging bongo

Post by benedmonds » Sun Jul 15, 2012 10:27 pm

My bongo is grounding out if loaded when if goes over speed bumps or bumpy ground. What can I do??

I thought it was the exhaust to start with but it is the two round bits next to the back wheels. I've got some photos but can't post them for some reason.

common problem

you can get air assisters for the rear springs and I'm sure some one will come along with the correct type etc

Its cheaper than renewing the springs

see if you have the rear bump stops in place,one or more usually fall off. they are the 3 inch solid blocks of rubber bolted up to to the underside of the chassis, these hit the top side of the axle tube. if they are there you could remove them and fit a softer compound rubber block. works well for our 2 bongo's. same size , just a softer hit.

I fitted these a couple of months ago and they have transformed the rear end. The Bongo used to wallow a bit going round country lanes and bottom out going over speed humps. Fitting these has cured both problems.
Fitting is not quite as easy as their video would suggest although I managed in just over an hour.

Mine bottoms out when loaded too. These look just the ticket. Looking at the installation instructions they look straightforward, but are there any top tips. Also what psi for general use cheers rob

I use about 45/50 psi which seems to cope even when loaded. I think the instructions say you can go as high as 100 psi but I'd guess at that pressure you'd have a pretty harsh ride.
As for installation, the instructional video on the site explains it all quite well but I'm sure the bloke doing the fitting has done it a hundred times before. The actual bags are very tough vinyl which is quite difficult to manipulate through the coils. Strong fingers are needed and a tool such as a tyre iron is essential.
Oh and put the hose on at the bottom, not the top, you'll see why. Make sure you use the correct spacer at the correct end. Its not that clear. I can't remember which is which but e mail the supplier and they will explain.
