Have located the leak on the rack, it is leaking from the housing below the steering column connection, it is an ally housing with a centre bolt or screw fixing. HELP!!!!! what can i do? ? First Tony, is the leak actually from the housing and not a seal where the shaft enters the housing? You need to check this very carefully. I know it can be difficult because of the location - this why a mechanics job is often awkward. Sometimes the only option is to strip down for access. You need to clean the area with something which will wash the oil away, and evaporate itself, leaving the area clean and dry. If it is difficult to get at, then some carburettor or brake cleaner is probably best. The spray from the can should be powerful enough to wash the oil away and they will evaporate afterwards. If the leak really is from the housing, it suggests that either the housing is cracked, or porous. It is probably more likely that it has cracked, and the crack will start from where a pipe or union is screwed in. This has probably been over-tightened causing the crack. To repair a crack (or porosity) in the casing, you need some 'liquid metal'. This is usually two tubes of chemical compounds that when mixed, will set hard and become just like metal. Loctite and Araldite, are two common ones and there are others around. You want the ones that form a metal, not the more normal glues that these companies sell. As long as the metal surface is totally clean and oil or grease free they work well. You may need to drain the oil from the system to stop the oil seeping out and spoiling the surface you need to repair. I have used them to seal porous casings, rebuild damaged surfaces, seal cracks etc. and if done properly, they work well. Roy

I have found the leak, its on the shaft entering the housing. When engine is running it is now possible to see fluid leaking from shaft housing. I think it would be better to obtain another rack and replace the faulty one. I have noticed while phoning around for quotes for fitting a new rack most of the garages local to me will not touch the job, I know it can be a long job. I would do the job myself but i dont have the tools to do it.
The job is a days work with the right equipment and knowledge. You really need a vehicle lift, and two special tools, which means it is not a home job. Also if your rack has a 50mm short valve housing and you replace it with a rack that has the 60mm long valve housing, you have to replace one of the hose/pipes too. The rack has to come out from the left wheel housing not the right. If you have an auto gearbox the job is even worse, as there is another half a days work. Sorry to give you bad news, but this is probably why most garages don't want to touch it. When you say the leak is from the shaft, I presume you mean the seal where the shaft enters the housing is leaking? So it really needs a new seal? Where do you live Tony? Roy
