The Loctite solution seems to have worked well for me, although I used Loctite Blue. If it ever starts to slip again, I'll clean the splines as suggested by another poster and then use Loctite Red. My biggest concern then would be getting it apart again, but since it's a taper fit, I think a battery...

Strange coincidence--just this evening I installed a pair of aftermarket headlight assemblies I bought off eBay from a seller named volvonest. They're not OEM, but the quality seems good, with glass lenses instead of plastic. I got the pair for $126 plus shipping. I also installed PIAA Intense White...

If you're going to the trouble of pulling the throttle body, I strongly recommend replacing the original throttle plate with a 960 throttle plate. Order the screws and a throttle body gasket at the same time. It's an easy, inexpensive mod that provides a little more throttle response. Someone posted...

Anyone able to rate the XC90 spring seats versus IPD's HD spring seats on an 850? I was planning on using the IPDs, but if the XC90 seats offer the same benefits for less cost, I'd consider the swap....

They've given me the best prices I could find anywhere on genuine Bosch components (air mass sensor, O2 sensor, fuel filter), as well as ND Iridium plugs and a K&N ai...

It could be the fuel/air mixture detonating (aka pinging) in the cylinders. Detonation can sound exactly like a baby's rattle, and it usually happens only during acceleration. Have you recently changed brands of gasoline? I'd try filling the tank with some 91-octane premium, or at least adding a dos...

If you do need to replace your coil, I recommend the MSD Blaster coil setup from IPD. Yeah, you can buy the coil cheaper from Summit or other online sources, but you won't get the custom coil bracket or coil wire. I was amazed at the difference the replacement coil made, from idle all the way throug...

I recently replaced a bad MAF sensor on my '94 850 N.A. I shopped around on the Internet and found the best deal at www.autopartswarehouse.com. OEM Bosch part, brand new in the box, for $139, free shipping. Good luck!
