Also check the adjustment. I had a knocking from the steering on the LSE, turned out the arm could rock back and forth, it was way loose and I'm surprised it didn't leak. Anyway I was able to adjust it and now it's fine, I've avoided having to buy another.
Funny thing with the LSE, lots of stuff seems to be loose, the N/S exhaust manifold is blowing again, all the bolts have worked loose :?
