350i Steering Rod bulkhead bush
Discussion
The steering on the 350 is feeling a bit vague as you begin to turn the wheel. I have replaced the rack and everything else including the suspension seems fine. I suspect the bulkhead bush is a little tired. The steering rod appears to be about 3/4 inch in diameter. The car is 1988. Is there a replacement bush available or modification ?
Non power steering.
Many thanks in advance.

Although in my limited experience (two failed bushings on the 280i) the stock bushing doesn’t fail a little, it falls apart completely and the steering column flops around. Here is one of the threads: http://www.pistonheads.com/gassing/topic.asp?h=5&a...
I bought the US version of this bushing and may get it installed this weekend. Grady

Did you do it yourself and if so any installation tips (oops "tips' may cause issues) Grady
Yes did it myself; it can be a bit tight to get the top knuckle back in, I had too nock the intermediate column all the way down onto the steering rack splines (removing locating and clamping bolt first) to get the top knuckle out but because the new bearing set up sticks out slightly further than the old bearing; I had to slacken the actual steering rack brackets on the chassis and move forward slightly to get the knuckle back in.Also when you do it, make sure that none of the columns (top or intermediate) stick through the top knuckle further than before and catch on the knuckle block when turning. Other than pretty simple and as said above certainly feels better, even though original bush was still in half decent nick, that said didn't quite achieve the lighter steering I was hoping for on a none power steering set up

All I got from the above was 'sticky top knuckle certainly feels better, and rack'

Afternoon boys and girls...
Done this on my 350i very recently....
I used this part...

Mounted INSIDE the footwell to make sure there is plenty of room for the UJ at the top of the steering shaft, does make a tremendous difference, wish I'd done it years ago.. The grub screws bite down onto the 3/4" splined section of the SD1 steering column.
PS:- I have one of the pressed steel types shown in the pictures sat in the garage which is available in exchange for beer tokens if required BNIB.

Now featuring power steering... now that DOES make a difference!

This bearing on the inside seems like a much easier job than the one on the outside. As folk have pointed, with such a small space between the join in the steering shaft and the bulkhead, getting a bearing on the outside means it will have to point inwards. Comparing the 2 bearings (yes- I bought both because they were only a few £!): if you fit the one on the left (on the outside OR the inside) you have to take the hole in the bulkhead out to 50 mm accommodate the lip. The other one will sit flush, but would have to be fitted on the inside:Done this on my 350i very recently....

Just interested in any thoughts or good reasons why the bearing should be on the outside?
Hi Peter.
I had a Citroen saxo Electric PAS pump fitted to my 280i..This was only done as to make room for a supercharger...However I cannot say that the steering felt any better...But then it was for a space reason.
It needed a 50amp fuse and I had to upgrade the alternator as it drew a fair amount of juice from the battery...I did have a switch fitted so that it could be switched on if the engine failed..That was a killer on the battery though...

the car started it's life with power steering . but someone along the way changed the rack. i've bought a re -oned rack but am a bit stuck on how to fit , where the pump goes and where to get the pipe work done . any info would me much much appreciated . thanks for the info about the saxo rack . hadn't thought about the draw down on the battery.
