Anyone happen to have access to the shop manual for a 1995 Chevy K1500 series pickup? I just completed a major upgrade to all the front suspension components and ran across something that didn’t sound right when I reassembled it.
The Chilton’s manual I have states that the “splash shield bolts”, which also happen to hold the unit bearing hub to the steering knuckle, are to be torqued to 19 ft-lb. These three bolts, which are approx 5/8", seem like they should require more torque. (The CV shaft spindle nut is torqued to 180 ft-lb for comparison).
Anyone have experience or the book on this truck to verify?
Yeah, that ticks me off too.
It’s not worth much, but unless a bolt goes into aluminum or is something like a head bolt I don’t worry about the torque, just tighten it down.
Cool. Taking it over for an alignment tomorrow and to get the freon removed. I’ll be bringing it into DMS to R&R the compressor/accumulator, vacuum it down, and charge it. Last compressor (from Compressor Works in Dallas) lasted 5 years … hoping that an AC Delco unit will last longer this time.
Not sure what you mean by “which also happen to hold the unit bearing hub
to the steering knuckle” , but the splash shield is just an air deflector
that usually is plastic or aluminum that bolts to the frame. 19 is enough
for that. 5/8 bolts sound like something else.
AC compressor last for many years, unless the system is contaminated,
improperly charged, over charged, insufficient oil, or to much oil.
I have 12 years on my AC Delco compressor and still going strong.
Autozone lends 'em. That’s what I used last time. Would be nice if the space had a R-134a reclamation/charging setup. I’ve got the Haynes book on it, and it wasn’t too difficult. Just attention to detail.
In the case of the K1500, the “splash shield”, or dust shield is #6 in this image:
However, mine is more like 90 degrees and has only two holes. When removing it, it was attached to #1 so that it did not interfere with the brake caliper, and the bump in the shield provided clearance to the ABS sensor, so I think I have it on there correctly.
There are three bolts which attach #1 to the steering knuckle (only part not labelled in this diagram). They are metric bolts (15mm head) marked 10.9 (grade, I think). The only torque spec I can find would have me attach the “splash shield” with 19 ft-lb, and since the bolts which attach the splash shield are two of the three which attach the hub to the knuckle, this is what bothers me.
As for the AC compressor: My 15 year old Celica is still going strong. The AC Delco unit which was originally in the truck blew all its freon out the front seal, and the replacement from Autozone lasted 5 years. I flushed the lines per the instructions, pumped it down, checked for leaks, and put the correct quantity of freon back (by weight). It is likely that “Compressor Works” just did the bare minimum on a compressor rebuild.
Always obsessive about automotive. GM did lots of research on improper
torque due high number of lateral run out claims and it was cool to see how
improper torque effected hubs. The reason I own high end torque wrenches.
