Wheel bearings do not fail promptly, and usually Provide you with some time in advance of you might want to have them changed. I suppose if a wheel bearing failed wholly it could lock up and stop the car from transferring.
It truly is probable you're Listening to a wheel bearing sounds but You furthermore mght could be Listening to just tire sound. I like to recommend inquiring one of many on call mechanics to Opt for a journey with you so you can talk to them in regards to the noise prior to buying it.
I now feel self-confident to check out my garage with a good strategy of what's Completely wrong with my elderly nonetheless continue to sprightly Merc R170.
If you would like Check out a few matters and acquire back to me with some far more data/questions, I’d be satisfied to attempt to help you thru your challenge.
2) the vacuum change (Found on the firewall — see among my posts higher than for an image) or vacuum diaphram (Found underneath the battery) may be malfunctioning. The task of such components is to pull on the cable which engages the front, proper 4WD hub.
My front tires are Wintertime tires and therefore are cupped and I know I would like new struts. Could these two be the reasons for this noise or is it something else?
Heck, if ya need to “hack†it collectively, you may usually take away the module from your side of the transfer scenario, cut a hole through the flooring and set an precise shifter through the floor and connect it to the pin over the transfer scenario (I wouldn’t advocate this on an ’03… maybe leave that trick for one that is slipping aside and also you don’t want to invest A further dime on it!) — You'll be able to shift into 4WD manually (Yet again… NOT Advised on a Avenue car or truck!!).
If there is absolutely no sound and the wheel bearing does not have any play there isn't an issue however and it might just take a long time for there to generally be a challenge according to driving behaviors, affliction, and miles driven.
I am bringing it back to your dealership, do you think that the dealer would deal with this? I'm undecided what the guarantee can be or just how long it's excellent for.
The challenge, as I learned, was corroded wires during the 4×four module. The module is found at the rear of the kick panel within the travellers side (see picture down below). How did I'm sure this? Anytime I'd personally engage my 4 wheel travel, I'd personally hear a “click on – click on†coming from that region… never assumed just about anything of it ’til now!
I dont have an issue but this seriously aided me diagnose my vehicle! Its gonna be a costly correct for us sad to say but at least we confirmed exactly what the shop reported.
What it appears like is you'll have an encoder motor challenge — this is the motor over the facet from the Transfer Case blog that controls the shifting of the various “modes†(2Hi, 4Hi & 4Lo).
What you explain looks like the ported vacuum change (Be aware: this change is barely on 1999 and up cars). I’m not sure around the “Listening to something managing†— Exactly what does it seem like?
The opposite wire I might Test can be the A/T (Automated Transmission) shift lock switch — This can be wire #31 and is particularly light inexperienced using a black stripe (there are actually far more web pages with the schematics higher than… the main is usually a hand -written webpage in the TCCM connector pinout). This wire should have voltage placed on it at particular periods — sad to say, I have never needed to diagnose that Portion of the program, so I don’t know if it ought to be +5VDC or +12VDC (but It will likely be one of these!
