#4941 of 11964 Redline transmission oil by boxtrooper

Jun 25, 2002 (1:17 am)

Kong,

I used the RedLineOil telephone help to get a recommendation of what synthetic oil to use. The guy on the phone seemed to know his product well. I told them my reason to go to synthetic was for better protection when towing my 4000 lb. trailer. They recommended RedLine MTL for my manual transmission. MTL is formulated for easier shifting while still being heavy enough for the synchronizers to work.

The effect of the MTL is much easier shifting. Still not as easy as my previous 1984 Trooper-II 4 speed, but a lot better than my 1995.5 5 speed was with the original Isuzu oil in it.

I put redline in my XT6, didn't notice much difference, but that may be because I have a bad rear diffy in it currently. We'll see what happens after I replace that.

Are you factoring the mileage difference due to the larger size?

#4944 of 11964 Laughing as I hang up on dealer... by tetonman

My 99 S is due for the 30k services. When my wife called the dealer we bought the truck from, she was informed that they no longer carried or serviced Isuzu trucks (one less dealer in Chicago). She then called two other dealers in the area and was quoted $600+ for the service.
 
Going through the manual and then calling around to other ASCE certified shops lowered the cost significantly. The thing that bothers me is that the dealers wouldn't do only the maintenance required by the owner's manual. They added in a lot of extras.
 
Now I read that many dealers and manufacturers are not giving their vehicle codes to independent repair shops, forcing owners to use the dealer service department. What a mess! No wonder dealers have such a bad reputation. If you are going to force us to use you, please allow us the option of only getting the RECOMMENDED services only and not all the other garbage tacked on.
 
Sorry for the rant. At least I have a good truck that isn't being recalled every 6 months for repairs or falling apart.

#4945 of 11964 re: mileage by sbcooke

I do the calculation actual miles = odometer*(new diameter/old diameter)...roughly (30.5/29.5) 1.03 times. So last tank was 160 miles --> 165 actual / 13.5 gallons.
 
This is only my second tank, and I do a lot of idling...it rained last week with about 85+ temps, so I sat in the A/C for 15-20 minutes at one point. It is hard for me to get an accurate mileage based on driving, but in general it seems down 1-2 mpg.

#4946 of 11964 1offroader ... rattle by savvas_e

Hey 1offroader,
 
Can you describe the rattle that you were getting? Was it like a small component rattling loose, or did it sound like something big (like a back door)not quite fitting tightly and drumming away?
 
The one thing I find most annoying on my Monterey is some drumming type noise coming from the back, over rough paved or hard surfaced roads and tracks. I don't get the noise on gravel or dirt.
 
I always suspected that it might be either the rear barn doors, or possibly the roof panel (however, the roof panel ribbing should stop that drumming). Haven't been able to figure it out. I'll give the spring solution a go.
 
If I can get rid of this, then I'd happily say that I have the "closest to perfect" car that I have ever owned.

#4947 of 11964 Tetonman....Hang Up On The Dealer by schulhof1

Tetonman,
My local dealers are useless as well. Same deal as you. My (now 108k mile) Trooper was last serviced by the dealer at 15k miles. Ever since at an Independent NAPA repair shop.
 
They let me call the shots. I tell them "I have 90k on the car, I want you to do X,Y,Z". No BS.

#4948 of 11964 dealers by bluedevils

Our Trooper isn't serviced at an Isuzu dealer any more, but in the past at least my nearest dealer has been willing to do only the things that I ask them to do.
 
I can't believe a dealer would refuse to quote a price for work on a job-by-job basis. I guess they know the real profit lies in lumping it all together, calling it the 'official xx,xxx mile service,' and charging more for the whole thing than the sum of the parts.
 
tetonman, what exactly did you mean by "many dealers and manufacturers are not giving their vehicle codes to independent repair shops"? Of what vehicle codes are you speaking?

#4949 of 11964 more rattle info by 1offroader

Jun 25, 2002 (8:20 pm)

The rattle sounded like a loose marble inside the tailgate, not a 'drumming' sound.
 
More info. on the fix. Once the two bolts are removed and the sliding gizmo is off the door, it comes apart without tools. There are four components - the mount or housing, the white nylon/plastic wedge, the rod, and the spring. Actually, I replaced the single factory spring with two springs. I couldn't find a single spring long enough, so I bought two shorter, stiffer springs of the same diameter as the factory spring and mounted them end-to-end on the rod. Once I figured out what to do and found the new springs, the repair took about one minute - literally.
 
It's a very simple repair. You do not need to be a Master Mechanic to do this. All you need is the wrench or socket to remove the two bolts. Finding the appropriate spring(s) will be the most difficult part of the job.

#4950 of 11964 Rancho RS 9000 Shock Settings? by radman6

Jun 25, 2002 (8:29 pm)

I'm curious what settings people are using on their Rancho shocks. I've had mine on for a few days at the three setting and the ride is pretty harsh. No more bouncy ride - just one solid bone jarring jolt when you hit a bump.
   
  I may have to break down and try the two setting. Hmmm, wonder if I set them on the wrong number in the dark with my flashlight. Feels more like a five setting.
 
  For those with Rancho's - did ride change / improve after a break in period?
 
  I've had Ranchos on three other vehicles and never noticed this much difference before (in terms of stiff / harsh ride). Maybe it's because the Trooper had such a cushy ride before.
