NigelH Posted June 29, 2019 Report Share Posted June 29, 2019 Hello All, I have developed a chatter noise at low speed that speeds up to a whine. Been under the car and the UJ at the diff end of the pro-shaft has freeplay, unfortunately it looks as dry as a bone grease wise.. Can the propshaft on a TR4 be removed from below, rather than pulling out the tunnel? Any advice is appreciated. Thx Quote Link to post Share on other sites
RogerH Posted June 29, 2019 Report Share Posted June 29, 2019 Hi Nigel, You will need to have a wheel free so that you can rotate the shaft to get at the bolts but the shaft should come out rearwards. Roger Quote Link to post Share on other sites
Lebro Posted June 29, 2019 Report Share Posted June 29, 2019 In my experience propshaft UJ's don't usually whine, when worn they "clunk" on take off, then at speed you may feel a vibration as the shaft moves off center.. Sounds more like a wheel bearing to me, or maybe pinion bearing. Bob. Quote Link to post Share on other sites
Chilliman Posted June 29, 2019 Report Share Posted June 29, 2019 +1 for that Bob, but the fact there is identifiable slack in the rear UJ is good enough reason to pull the prop & replace the joint anyway - get that done first & see what's left to deal with... it should be easier to identify if the UJ's are in good order Quote Link to post Share on other sites
NigelH Posted June 29, 2019 Author Report Share Posted June 29, 2019 Thanks for the all the advice, caught a video on replacing UJ's on Youtube and the sound i get is exactly the same at low speed and as it speeds up, eventually disappearing all together (more of a metallic screech..screech..screech than a clonk, at low speed.) Will change it out anyway as its worn, (its moving about a 2mm when I pull and push on it) and see if that solves it.. Thx.. Nigel Quote Link to post Share on other sites
RogerH Posted June 30, 2019 Report Share Posted June 30, 2019 Hi Nigel, if you haven't already got your replacement UJ's have a look here https://www.jgs4x4.co.uk/search-results?q=tvc100010gx2 Roger Quote Link to post Share on other sites
NigelH Posted July 5, 2019 Author Report Share Posted July 5, 2019 Update.. Got the car up on a mates ramps.. I can't get to the front UJ's bolts from underneath, so its tunnel out. Front UJ is in worse condition than diff end.. both are 'squealed for life' types. Roger thanks for the link, I'd had ordered a UJ..before seeing the link, but reordered another from the site you suggested..its much more substantial (wider bearings) than the first one I ordered. Another on its way.. Birthday money spent, wife wanted me to have a T-Shirt.. Thx. Quote Link to post Share on other sites
Malbaby Posted July 5, 2019 Report Share Posted July 5, 2019 What is stopping you from accessing the front Uni bolts. Quote Link to post Share on other sites
NigelH Posted July 13, 2019 Author Report Share Posted July 13, 2019 Malbaby, Flange bolts are directly inside the box the exhaust runs thru, can't reach them. Thought it would pull of the spline in the prop but it wouldn't /shouldnt? Planning to strip out interior next week and get U/J's done..and MOT. Quote Link to post Share on other sites
Malbaby Posted July 14, 2019 Report Share Posted July 14, 2019 Ok...my car chassis is not boxed there. What about cutting the box to gain access and then reweld. May be easier rather than removing the interior/tunnel. Quote Link to post Share on other sites
NigelH Posted August 10, 2019 Author Report Share Posted August 10, 2019 Hi All Update on the UJ saga..had to remove the interior of the car to get the Prop out.. 2 days of work, but done now, and runs very smoothly now.. Put in all the holes and splits in the tunnel as per other forum conversations.. In removing the radio and dash support bracket (that straddles the tunnel) I have found that someone has cut the support bracket down in height by 4" at some time..so now in the search for a replacement that is complete..if anyone may know of a source of one I would really appreciate the lead.. thx Nigel Quote Link to post Share on other sites

rcreweread Posted August 11, 2019 Report Share Posted August 11, 2019 Nigel - the proper TR4 H frame finishes about 4" below the bottom of the dash and the gap is filled with the "radio plate" bracket ( not sure the correct terminology) which bolts to the top of the H frame and underneath of the dash and fills in the gap - if yours looks like the one on ebay ( link posted above) then that is correct. Otherwise I don't understand how it can be 4" cut down - can you post a pic? Cheers Rich Quote Link to post Share on other sites

Can be solid or with cutout for radio. Face can be slightly convx or be recessed to all the radio knobs to sit inside. AlanR Quote Link to post Share on other sites
RogerH Posted August 11, 2019 Report Share Posted August 11, 2019 Hi Nigel, see items 110 and 92. https://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/interior/dashboards-consoles/dash-fascia-tr4-4a.html That ebay offering is from Helen and Ray and a nice price.

NigelH Posted August 16, 2019 Author Report Share Posted August 16, 2019 Thanks to all for the information. There is a phrase " make a fool of yourself at least once per day".. The bracket is as original, my radio bracket was made up of several parts, which lead me to think the bracket was cut back. Just ordered a one piece radio bracket.. Nigel Really appreciate the advice/guidance. Quote Link to post Share on other sites
