Thread: Front end growling/groaning really worrying me

    Default Front end growling/groaning really worrying me

    A while back I posted about my front end making noise on turns. Jeep is a QT-II with 100,000 miles. It's in great condition. Previous owners took very good care of it.

    I'm noticing a lot of groaning/growling when turning. Not even full-wheel-lock situations, but turning a U-turn or pulling into a driveway will cause the noise. Some situations you can expect it and others it will do it one moment but not the next.

    I changed the fluid in the X-fer case with the correct fluid for the 247 TC. It was filled to the proper level. I'm wondering if I need to drain and service the front diff or look at replacing cv joints?

    Power steering fluid is low or pump is going?

    Growling and Groaning? Yikes. Did you check for Tigers or Bears under your hood?

    Seriously, though, Does it make the noise when you are stopped, or when you are moving? If only when stopped, its probably your PS pump. Check the fluid and top it off if needed.

    I have the same problem. It isn't the power steering pump. It doesn't do it with the front drive shaft out. I am thinking T-case.

    Man, look at your front drive shaft... if it has a cv joint (Repezza, I think is what it's called) on either or both ends then inspect the boot(s) and see if there might not be a spray of lubricant on the underbelly of the Jeep. Mine was making all kinds of noises, growling included, and I replaced the drive shaft and it cured every issue.

    Could be your power steering gear box is going out.

    Have you checked wheel bearings? They will make growling noise when turning.

    Do a series of sharp figure eights in both directions. Leave the windows open and have a friend watch the front tires.

    kadetklapp... Have you figured out what the issue is yet?

    Billy-Ray... by turning the figure 8's and having a friend watch...what are you watching for and what are the possible symptoms indicate or lean you to and away from determining what the problem might be?

    Mechanic friend of mine drove it and thinks it's the cv shafts.

    Speaking of which, I got online at Autozone to price some new shafts. Just to get a rough idea of the cost on parts. There is this ominous warning in the "Notes" section:

    Application:
    Left hand side (Sitting inside vehicle)
    Without quadra-drive
    Warranty:

    LLT
    Notes:

    Engine alignment is critical for this application. Strongly suggest replacement of motor mounts
    Now, what in the world does "engine alignment" have to do with this? I thought maybe it was just a universal warning given on all cv shafts since FWD cars use them too. I looked up my wife's G6 and no such warning was given. Any ideas?

    Never seen that before. Basicly there saying make sure the motor mounts are good before replacing the cv shafts. By having a bad motor mount it would throw off the engine alignment.

    Looks like a general warning/suggestion/sales-pitch to check the motor mounts. As huey113 mentioned if mounts are worn enough it could extra stress on CV because of engine mis-alignment.

    That is the typical warning for front wheel drive vehicles. Since most of those are equipped with half-shafts using CV joints. Some "clerk" enters this information on their website. As mentioned it also can be used as a selling point. The other thing if that warning was Jeep specific they would mention the transmission and TC mounts as well.

    Engine position has nothing to do with axle half shafts (cv's).... But driveshaft and pinion bearings could.

    I 2nd the wheel hub/cv needs to be examined

    This is a simple fix. You said you recently changed the diff fluid right? You'll need to add the anti slip additive to the differential as well. I had the same problem when I changed my diff fluid and couldn't figure out what it was. Put in the anti slip additive and it went away.

    my mistake. you said you changed the transfer case fluid, not the diff fluid. could be that you need to change the diff fluid and add the anti slip juice.
