Hi Ian. I was wondering if you have any experience or know of any mechanics
that service ISS problems on W-body vehicles?
My vehicle is making clunking sounds when turning and when deaccelerating.
Having doing some internet research it appears as though GM recommends the
ISS to be lubed. Isn't this a temporary fix? Once my 3 year warranty
expires I have to pay each time it requires more lube. I have read that the
procedure is quite a bit of work and will cost about $150.
I cannot imagine why a huge company like GM can't solve their steering
issues and have nothing but temporary fixes.
Thanks In Advance,
My wife's started doing that just before the warranty was out. We didn't
have time to take it to the dealer and I wondered if it may be temporary as
well. I found the tsb took the lube kit part number and went to
gmpartsdirect.com and ordered it for about $. It took me a couple hours to
pull the ISS as its a tight squeeze, but I got it out, put the grease in
and put it back in and we now have put 10k more mile on it since. Its my
understanding that the shafe is designed to be lubed for life like all new
steering parts and just didn't get enough lube at the factory so its not
supposed to need it done again. I think though if I ever have to and would
suggest to you try this. Just unbolt the iss from the steering wheel end,
stick a grease gun in and give a few pumps, then find something to plug the
shaft like a cork or rubber ball (the kit had a rubber cork). Plug the
shaft hole and work the shafe in and out a few times, then remove the plug
and connect it back up. I think it can be done inside the car with only
the one end disconnected and the steering wheel end is easier to disconect
than the rack end and IIRC the hole for the grease is at that end too.
Yeah, what Eugene Nine said. Though I would add that I've watched
the front end guys install the grease, and they stick the shaft in a
press in order to get the grease inside the shaft. It seems to work
fairly well for most vehicles, but we have had some vehicles that
keep coming back.
Has the problem been corrected for 2004?
Seen a few 04's at one dealer. The LS now has smooth finish body colored
mouldings, instead of the rough textured black ones. Also gone is the
black rough textured rear bumper insert in the depression for the
license plate. I see they have a Medium Grey Metallic color like the De
Ville offers but calls Thunder Grey.
