I am trying to replace the spark plugs in my 2003 gmc sierra 1500 5.3L
4wd. I have got all but two done with. One giving me trouble is on the
passenger side, nearest to the firewall. The other one is on the
driver-side, second nearest to the firewall. I think to be able to get
to the second one it is necessary to dis-assemble the shaft leading
from the steering column to the front axel. I have no idea how to get
to the other one though... There doesnt appear to be enough room to
get the spark-plug socket on the spark plug while also getting the
wrench in the socket... any tips?
How about putting the socket on the plug then putting the ratchet handle on
WRT the #7 spark plug, you might try removing the LF wheel and going in that
with a flex ext.
Have no prob with either on my 97 Yukon SLT.
On my '04 Z71 Avalanche, they can both be removed with a 3/8 ratchet with a
short 1" extension to the spark plug socket. Doing it with no extension
(just the spark plug socket) or the standard 3" extension causes clearance
